Hey readers I am not trying to make you math genius but just teaching you some techniques which might be helpful to you in your life somewhere. Won’t it look cool if you can do some mathematical calculation without calculator when you need them at instant and when you don’t have calculator with you? It would be like a great help to you and you could be bit of smart in front of your pals around you.
Today I will write about how to make a calculation with 11. When you calculate any number with 11, you have to work with this formula
11* XY = X (x+y) Y
Well this is the formula to calculate by 11. Let’s get through some examples
11*22 would be 2 (2+2) 2 which is 242
11*39 would be 3 (3+9) 9 which would be 429.
It’s easy and cool enough and you don’t need calculator anymore for multiplying anything by 11.
