Find the missing digits.
- R
- S
R619 - 14S3 = 7136(a)
In the hundreds place, 6 is more than 4.
So, there is no regrouping in the thousands place.
R - 1 = 7
R = 7 + 1
R = 8
(b)
In the ones place, 9 is more than 3.
So, there is no regrouping in the tens place.
1 - S = 3
In the tens place, 3 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 3.
S = 11 - 3
S = 8
Answer(s): (a) 8; (b) 8
