It was an hour-long debate with Rehma, as per she, mathematics is the toughest subject, to whom I disagree completely! for me it was a game based on numbers, where you just need few tips and tricks to understand the basic concept of math and use it to make your life a little fun.

For example, lets talk about the **divisibility rule**, to have a smart edge over everyone else. It will help you to divide in situations where your parent asks you for a quick calculation or you want to divide the share of your bill amongst friends but alas don’t want to pull out a calculator.

- First one is easy
try it!__Every even number is divisible by 2:__

- How to know that a number is divisible by 3 or not? Simply
, if the answer is__add all the digits of that number__**divisible by 3**than the whole number is.

**For example**. Want to divide

**8,976 by 3,**lets figure out, can it really be without any remainder?

8+9+7+6=**30** and yes you don’t need a calculator to figure it out that **30** does come in the table of **3**. The number **8,976 **is completely divisible by 3 i.e. **8,976 divided by 3 **= __2,992.__

__ __

a piece of cake, if__Divisibility Rule for 5,__**number ends**with a digit**0 or 5**than close your eyes and divide it by

__ __

Well this one is quirky, first take the last digit of a number than multiply it by 2, subtract the answer with the remaining digits. If it comes in table of 7 than the whole number is divisible by 7, if it is still big repeat the step again and again and again…__What about 7?__

**For example. 6,909 **is our number to be in question, lets take its last digit i.e.

**9**multiply it by

**2**answer is

**18,**now subtract

**18**from remaining digits

**i.e. 690-18= 672,**well number is still big lets do it again! Take last digit i.e.

__2____multiply it by__

**2****= 4,**subtract it from remaining digits i.e.

**67-4=**

__63__Walla! **63 does come in the table of 7 so the whole number belongs to 7.**

Few things to note here, to make math easier, learn tables from **2 to 9** that’s all, and here I have taken the first few ** prime numbers** to show the divisibility rule,
