How to Solve Math Problem Faster

If you want to improve your problem-solving skills and become faster in math, you need to the ways to calculate large numbers without wasting too much time. There are several problem-solving techniques which can help you do your problems faster so that you can focus on bigger concepts instead of wasting time on small calculations. Here are the 5 tricks of doing fast math.

Addition

Addition of numbers is the quickest method in math, but it can be even quicker while adding two large number. This method of addition involves bringing the number closest to a multiple of 10. For example, 768+363 will be added below.

Rounding up 768+2=770 and 363+7=370.

Now when we add the rounded up numbers, we get

770+370=1140.  Now we determine how much we added to the numbers to round them up, which was 2 and 7. Subtract 2+7=9 from 1140, and we get 1131 which is the answer to 768+363.

Subtracting from 1,000

When you have to subtract from 1000, just subtract single digit in the number from 9 and the last digit from 10. For example, you have to subtract 572 from 1000 then,

Subtract 9-5=4

Subtract 9-7=2

Subtract 10-2=8

So 1000-572 is 428.

Multiplying by 9

When you are multiplying a number with 9, follow these two steps to get a quick answer without memorizing the tables. Let us take the number 8 to multiply with 9. First, we subtract 1 from the 8, which is 8-1=7.

Then we subtract the answer of first subtraction from 9, which is 9-7=2.

The combination of both the number is 72, which is 9 multiplied 8 times.

The division tricks

Division can be very difficult for a lot of students by by ensuring that you complete you math homework on time, you can learn division quicker. Here are the ways to find out if the number is divisible with a number or not.

  • Every number is divisible by 1.
  • If a number ends with an even digit, it is divisible by 2.
  • If the digits of a number are added together to get a 3,6 or 9, it is divisible by 3.
  • If a number has two 0s at the end, or the last two digits are evenly divisible by 4, the number is divisible by 4.
  • If a number ends with 0 or 5, it is divisible by 5.
  • If an even number digits are added together, and the added number is divisible by 3, it is divisible by 6.
  • If the last 3 digits of the number are 0s or the last three digits are evenly divisible by 8, the number is divisible by 8.
  • If the digits are added together, and the answer is divisible by 9, the number is divisible by 9.
  • If the number ends with 0, it is divisible by 10.

Things To Consider While Buying LiPo Battery Chargers

LiPo battery chargers are the ones that are used to charge Lithium Polymer batteries. These are the batteries that you will find in modern consumer electronic devices. It is extensively used in the radio control and communication industry. It is very reliable and durable.

There are a lot of companies that are manufacturing both LiPo batteries and LiPo battery charges. Since the predominant electronics are using LiPo batteries, the use of LiPo chargers is inevitable. So while buying LiPo battery chargers, there are a lot of things that you need to take into account which we will see in this article. Check out www.product145.com to get better ideas about LiPo chargers.

Balance Charging

Almost all of the LiPo chargers have the capability to perform balance charging. Balance charging is a process in which the charger will make sure that all the cells in the battery are charged with equal voltage. This is one of the most important factors that you need to take into account because if the cells are charged with different voltage, then there are possibilities that the battery will be damaged or else the battery life will be affected in the long run.

Cell Compatibility

When you are buying the charger make sure that it is compatible with the battery that is used in the device. There are possibilities that sometimes it will not support the battery in the device. Some cheap charges are only capable of supporting 2s or 3s LiPo batteries. A little bit expensive ones will support all kinds of batteries that range from 1s batteries to 6s batteries. There are also a few fancy and expensive chargers in the market that is capable of supporting and balance charging more than a single LiPo battery at the same time.

Charging Current

Generally, the LiPo batteries have the maximum charge rate specified as 1C, 2C and so on. But in chargers, you will find the charge rate in Amps. There are possibilities to get confused between these two values. Hence to avoid the confusion, it is better to convert the charge into amps. For that, all you need to do is just multiply the battery capacity with the C rating. For example, if the battery capacity is 2.2Ah and the C rating is 2 all you need to do is 2.2 x 2 = 4.4. If you are not choosing the appropriate charger, it will have a big negative impact on the battery and also the device.

Power Supply

There are few batteries in the market that has a built-in power supply. Hence you do not have to worry about it. But if the battery is not equipped with power supply, you need to make sure that you buy the perfect charger for it. Make it a point to look for the correct watts. If you are messing up in this aspect, then there are possibilities that your charger might not work properly, or it will affect the device.

Maintenance tips for electric scooters

The electric scooters are the ones that runs with an electric motor. Its basic design consists of a deck which is supported by two wheels, for the rider to stand on. Power to the electric motor is supplied by a battery that can be recharged. In the urban setup, it is proving to a convenient mode of getting around. The battery is easy to recharge, you don’t need a license to use it, and it does not have to be insured. Maintenance costs are cheap as the following tips disclose.

Tire pressure

Maintain optimum tire pressure:

Use the recommended tire pressure on your manual. It should not be too low because this will make the outer surface of your tires to extend and press hard over the ground. Because of this, your tires will be worn out in a short time. Worn out tires have less traction on wet ground and are liable to punctures. If the pressure is too high, the tire surface area in contact with the ground is reduced, and you are likely to skid on slippery ground. Use a pressure gauge to constantly monitor your tire pressure.

Check if your tire has a leak by spraying soapy water over their surface. Effervescence indicates a leak which should be promptly fixed.

Battery Maintenance

While charging you battery, observe the gauge to check if it’s fully charged. Overcharging will destroy the electric cells of your battery. To extend the lifespan of your battery, charge it only when it has cooled. If the battery has a leak and chemicals (acid) drip out, replace it promptly.

To ensure you use your battery lasts for a long time, charge it frequently. If you are planning not to use your scooter for an extended period, charge the battery quarterly per annum to ensure its electric cells remain efficient.

Lubrication

Your scooter has movable parts that are in contact with each other: chain, brake linkages, and throttle. You should lubricate these parts once a week by applying the recommended oils specified in your manual. Lubrication reduces friction between the moving parts. Increased friction leads to wear and tear of movable parts necessitating their replacement frequently.

After lubricating, clean oil that has spilled on other parts of the scooter, because it will attract dust that may make the parts develops rust.

Chain and belt tension

While using your scooter, ensure its chain is not loose. This will increase the wearing out of the chain and its socket.

Also, ensure the belt from the motor that moves the chain is not loose. If it is loose there will be increased friction on it thus overheating will occur making it be worn out quickly. Use the instructions on your manual to guide you on how to achieve the correct tension.

Brakes maintenance

Regularly tune the brakes of your scooter using your manual. This will reduce wearing out of brake pads because of increased efficiency arising from proper tuning. Make sure the brake pivot is well lubricated to reduce friction.

Scooter cleaning

Avoid splashing or spraying water all over it. This will make water to enter the motor parts leading to malfunctioning. Water can also create a short-circuiting of the electrical system that may be harmful. When cleaning the bearing use a polar (organic) solvent to remove dirt before applying fresh grease onto the bearing.

Sunshine protection

Do not park your scooter in strong sunshine for long. The high temperature will:

Damage the battery of the scooter.

Bleach the external parts of the scooter

Conclusion

Electric scooters are gradually becoming a good mode of moving short distances in urban areas. They are cheap, easy to maintain and don’t give off greenhouse gases. By following the required ergonomics (safety precautions), you can enjoy the service of this machine and save some money that you would otherwise use for a taxi.

Which Professions Will Be Most Affected By AI?

Artificial intelligence is the beast and it is continuously taking over all the industries in the world. Some people are considering it to be a threat to their profession while others believe that it will help us become more efficient. Well, I believe that AI will bring poverty to the world by turning down a huge amount of professions in the world. The experts have revealed that more than 20 professions will be affected by AI till 2020.

According to my analysis, these AI professionals would also lose their jobs if they did not stop their activities because these professionals have already introduced a robot that walks, talks, and even thinks like humans. So, you can imagine that if a robot can think like the human, then it would definitely have the ability to create something even better than the humans.

So, these professionals should be afraid of the outcomes of what they are doing at the moment. However, we are not going to discuss the details because currently, we are going to talk about the professions that will be badly affected by AI. So, here is the list of professions that will be most affected by AI.

Drivers

The drivers should start looking for another job because the top companies have already started building the autonomous cars and there are some companies that are going to launch these autonomous cars in the first half of 2020. So, the launch of these cars means that the drivers will lose their jobs immediately and they would have to struggle a lot in order to find another job.

Accountants

The accountants are also at a greater risk because we are already using the machines that work completely like accountants. And if you go to a bank in a developed country, you’d see that accountants are just sitting in their chair without doing anything. So, this is a clear warning to the upcoming accountants that they should change their profession because there is nothing left for them in this profession.

Editors

Many editors have already lost their jobs due to the launch of different editing products but there are some companies where editors are still working on different posts. However, the time is about to come when human editors would disappear from this planet. However, this new change won’t affect the writers because machines aren’t sharp enough that they may replicate the creativity of a writer.

Hopefully, the writers aren’t losing their jobs in the near future. For example, if you are a writer, you can easily write a great conclusion for your essay while a machine won’t be able to do that. So, you are in the safe zone for now.

Translators

The translators would also lose their job due to AI because there are many tools that are now performing the job of a translator. And the most remarkable thing about these tools is that they can translate into multiple languages without taking any time. While an average human can only translate a text into 2 or 3 different languages. So, the translators should start worrying about their job.

Ever Wonder: What are vpns for?

Surfing the internet in a hidden way is becoming more and more necessary, this is due to hackers who can infiltrate and capture really very important information.

What are VPNS for?

Without a doubt a VPN is a very useful program or Internet tool, many Internet users use these programs with the aim of defending themselves. However, they do not know precisely what a VPN is for.

This great software is necessary, and you have to take into account that it serves for many things, thanks to the amount of benefits, features and functions that this program provides.

It serves as an extra layer of security

The vast majority of premium VPNS have extra encryption as a way of building browsing security. Generally these encryptions are military grade, so they are quite good.

This encryption is the main reason why they recommend that if you’re connecting to a public Wi-Fi network, you use an encrypted VPN.

Logging into any website or banking system over public Wi-Fi is very risky. A hacker could easily access your information. VPN encryption protects you against that.

Avoid censorship and geographic blocking

One thing we must be clear about is that in some countries there are blockages and censorship against some internet services.

Although many uses this program, to falsify the real location and manage to avoid any censorship that exists in their country.

So, when you use a VPN the internet communicates directly with the VPN server instead of your internet provider. So it creates a confusion and makes the internet believe that you are surfing from another country. Users use this method a lot to unblock certain content on Netflix.

There is also the case of China, which has restricted use of Facebook, many Chinese citizens use a VPN to enter this famous social network without problems.

Allows P2P downloads

This is because there are some internet providers that block this type of function (Learn More at Anonymania VPN Reviews), although there are also certain providers that make it difficult for you to use this function so that you don’t.

You can easily use a VPN to remove these restrictions imposed on you by your internet provider, and make any P2P downloads. On the other hand, it will also help you facilitate the download process, because as we know, some providers make the process more difficult.

This is because providers don’t like excessive traffic, and depending on the provider, users generally always download illegal things. With a VPN you can solve all this.

Accessing work while you’re on the road

An ideal feature for those with online jobs. Because the VPN can change the location.

This way, when you are away from the office, you can access your resources, such as documents, files, music and more. Although this is not the only thing, through a VPN we can also access the company’s shared resources, such as file servers, printers, corporate applications, intranet, among many other things. In other words, it makes it easier for us to communicate with our work.
