Find the missing digits.
- P
- R
P217 - 25R6 = 5631(a)
In the hundreds place, 2 is less than 5.
So, there is regrouping in the thousands place.
P - 1 - 2 = 5
P = 5 + 2 + 1
P = 8
(b)
In the ones place, 7 is more than 6.
So, there is no regrouping in the tens place.
1 - R = 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.
R = 11 - 3
R = 8
Answer(s): (a) 8; (b) 8
