656 x 106
We will round to nearest hundreds and then multiply.
106 is in between 100 and 200
100 --- 106 ---------------------------------------------------------------------------------------200
The nearest hundred?
It is 100.
Now,
656 is in between 600 and 700,
600 ------------------------------------------------------656-------------------------------------700
It is nearest to 700
So, the problem becomes
700 x 100
7 times 1 is 7, then we put the number of zeros, that is 4 of them, so
700 x 100 = 70000
