23x45=1035 so 1056-1035=21 so the number 23-21=2 this is the answer

Why are we first dividing aren't we suppose to add the least number?

Find digital root for 1056. 1+5+6=12, 1+2= 3 digital root should be less than or equal to one. Digital root for 23 is 2+3=5 so it will of form 3/5 for to exactly divisible we need to add 2 to numerator so answer is 2.

I don't understand why we should do 23-21 at the end can anyone explain this. And @Nikitha 2 is not the remainder. 21 is the remainder.

1056/23 = 45.xx,

45*23 = 1035,

1035+23 = 1058.

Difference between 1056 and 1058 = 2.

1056/23 = 45.91.

0.91*23 = 20.93 = 21(approx).

23-21 = 2.
