Find the missing digits.
- V
- X
V635 - 23X1 = 7264(a)
In the hundreds place, 6 is more than 3.
So, there is no regrouping in the thousands place.
V - 2 = 7
V = 7 + 2
V = 9
(b)
In the ones place, 5 is more than 1.
So, there is no regrouping in the tens place.
3 - X = 6
In the tens place, 6 is more than 3.
This means that there is a regrouping done in the hundreds place so that 13 can substract a certain number to get 6.
X = 13 - 6
X = 7
Answer(s): (a) 9; (b) 7
