Find the missing digits.
- D
- E
D724 - 39E2 = 5782(a)
In the hundreds place, 7 is less than 9.
So, there is regrouping in the thousands place.
D - 1 - 3 = 5
D = 5 + 3 + 1
D = 9
(b)
In the ones place, 4 is more than 2.
So, there is no regrouping in the tens place.
2 - E = 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.
E = 12 - 8
E = 4
Answer(s): (a) 9; (b) 4
