Find the missing digits.
- A
- B
A719 - 39B5 = 2774(a)
In the hundreds place, 7 is less than 9.
So, there is regrouping in the thousands place.
A - 1 - 3 = 2
A = 2 + 3 + 1
A = 6
(b)
In the ones place, 9 is more than 5.
So, there is no regrouping in the tens place.
1 - B = 7
In the tens place, 7 is more than 1.
This means that there is a regrouping done in the hundreds place so that 11 can substract a certain number to get 7.
B = 11 - 7
B = 4
Answer(s): (a) 6; (b) 4
