Find the missing digits.
- U
- V
U729 - 31V2 = 5587(a)
In the hundreds place, 7 is more than 1.
So, there is no regrouping in the thousands place.
U - 3 = 5
U = 5 + 3
U = 8
(b)
In the ones place, 9 is more than 2.
So, there is no regrouping in the tens place.
2 - V = 8
In the tens place, 8 is more than 2.
This means that there is a regrouping done in the hundreds place so that 12 can substract a certain number to get 8.
V = 12 - 8
V = 4
Answer(s): (a) 8; (b) 4
