Find the missing digits.
- R
- S
R943 - 54S1 = 1462(a)
In the hundreds place, 9 is more than 4.
So, there is no regrouping in the thousands place.
R - 5 = 1
R = 1 + 5
R = 6
(b)
In the ones place, 3 is more than 1.
So, there is no regrouping in the tens place.
4 - S = 6
In the tens place, 6 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 6.
S = 14 - 6
S = 8
Answer(s): (a) 6; (b) 8
