Find the missing digits.
- C
- D
C748 - 63D1 = 3357(a)
In the hundreds place, 7 is more than 3.
So, there is no regrouping in the thousands place.
C - 6 = 3
C = 3 + 6
C = 9
(b)
In the ones place, 8 is more than 1.
So, there is no regrouping in the tens place.
4 - D = 5
In the tens place, 5 is more than 4.
This means that there is a regrouping done in the hundreds place so that 14 can substract a certain number to get 5.
D = 14 - 5
D = 9
Answer(s): (a) 9; (b) 9
