# tricks for quick multiplication

**the base method of multiplication **

the method of multiplication is used to multiply numbers very close to the power of 10,100,1000,10000 and so on

so let’s kick off with the sum 9*8 now we all know that the answer is 72

first, we should learn the small number then we will try for a bigger number

**step 1**

take a box like this and write them

**step2**

then here the closest number is 10 so

when 10-1=9,and 10-2=8

so write -1 and -2 on the right-hand side

**step3**

The next step is to cross-play

9-2=7,8-1=7

in this case, every time comes the same number so take one of them,

so that we take 7

**step4**

On the right-hand side, you can see that and multiply them

here -1*-2= 2

so take the first 7 and the next is 2 and join them

so here is the answer 72
