Find the missing digits.
- C
- D
C945 - 48D1 = 4074(a)
In the hundreds place, 9 is more than 8.
So, there is no regrouping in the thousands place.
C - 4 = 4
C = 4 + 4
C = 8
(b)
In the ones place, 5 is more than 1.
So, there is no regrouping in the tens place.
4 - D = 7
In the tens place, 7 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 7.
D = 14 - 7
D = 7
Answer(s): (a) 8; (b) 7
