Find the missing digits.
- R
- S
R947 - 53S2 = 1585(a)
In the hundreds place, 9 is more than 3.
So, there is no regrouping in the thousands place.
R - 5 = 1
R = 1 + 5
R = 6
(b)
In the ones place, 7 is more than 2.
So, there is no regrouping in the tens place.
4 - S = 8
In the tens place, 8 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 8.
S = 14 - 8
S = 6
Answer(s): (a) 6; (b) 6
