Find the missing digits.
- A
- B
A254 - 67B1 = 2473(a)
In the hundreds place, 2 is less than 7.
So, there is regrouping in the thousands place.
A - 1 - 6 = 2
A = 2 + 6 + 1
A = 9
(b)
In the ones place, 4 is more than 1.
So, there is no regrouping in the tens place.
5 - B = 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.
B = 15 - 7
B = 8
Answer(s): (a) 9; (b) 8
