Quick Tips on Math-Unbelievably Simple Shortcuts
Are you constantly confused by those divisibility questions? Do multiplication and tables leave you cold? Steady on. Mathematics can be fun too, once you realize the magic hidden behind those numbers. If you have always found the subject unfriendly, let us teach you a trick or two that will really impress you. Ready or not? Here we go…
• Let us go through a little tip about divisibility. Have you looked at a long number and wondered whether it was divisible by 4? There is an easy way of finding it out.
1. Just take the last digit in the number and
2. Add it to two times the second last number. You have the answer!
3. Let’s take up an example:
Take the number 212334436. Is it divisible by 4? Let’s see. Take the last digit in the number i.e. 6 and add it to twice the second last number i.e. 3. Then, 6+ (2X3) =12. Find out if this is divisible by 4. In the example above, it is. Therefore the number 212334436 IS divisible by 4!
4. You can even use this tiny trick to find out whether a particular year is a leap year or not. Try it out yourself, right now! We TOLD you it’s fun!
• Let’s try out another fun trick! Have you always been confused by the relation between kilos and pounds? There is a simple way out. Suppose you are trying to convert kilos into pounds. How would you go about it in the shortest manner possible? It’s simple.
1. Just double the kilos and add a decimal point to the answer.
2. Then, just add the two together.
3. Let’s take another example:
For instance, when you try to convert 86 kilos, just double it. That will give you 172. Now, add a decimal point to 172, (or just divide it by 10). That gives you 17.2. Now add the two numbers, i.e. 172 and 17.2. The result is 189.2. So, 86 kilos would give you 189.2 pounds. Ridiculously simple, isn’t it?
• Finally, a useful trick that will help you in temperature conversions! Here is an easy way to convert Fahrenheit to centigrade and vice versa. You’ve got to try this out!
1. When you are converting Fahrenheit to centigrade, just take away 30 from it and then divide by 2. You have your answer in a jiffy.
Want an example? Try this:
74 degree Fahrenheit -30=44. Divide this by 2 and you have 22. So, 74 degree is 22 degree centigrade.
2. If you want to convert a temperature from centigrade to Fahrenheit, just do the reverse. Just double the number and add 2 to it. Isn’t that fun?
There are a number of shortcuts you can use to make mathematics easier and fun. The easy steps we detailed above are just some of the tricks used by experts to get that edge over others. Try out these math shortcuts today and stun everyone with your speed!
