Find the missing digits.
- D
- E
D957 - 31E4 = 3773(a)
In the hundreds place, 9 is more than 1.
So, there is no regrouping in the thousands place.
D - 3 = 3
D = 3 + 3
D = 6
(b)
In the ones place, 7 is more than 4.
So, there is no regrouping in the tens place.
5 - E = 7
In the tens place, 7 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 7.
E = 15 - 7
E = 8
Answer(s): (a) 6; (b) 8
