Find the missing digits.
- V
- X
V752 - 52X1 = 4481(a)
In the hundreds place, 7 is more than 2.
So, there is no regrouping in the thousands place.
V - 5 = 4
V = 4 + 5
V = 9
(b)
In the ones place, 2 is more than 1.
So, there is no regrouping in the tens place.
5 - X = 8
In the tens place, 8 is more than 5.
This means that there is a regrouping done in the hundreds place so that 15 can substract a certain number to get 8.
X = 15 - 8
X = 7
Answer(s): (a) 9; (b) 7
