Find the missing digits.
- P
- R
P947 - 23R6 = 1561(a)
In the hundreds place, 9 is more than 3.
So, there is no regrouping in the thousands place.
P - 2 = 1
P = 1 + 2
P = 3
(b)
In the ones place, 7 is more than 6.
So, there is no regrouping in the tens place.
4 - R = 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.
R = 14 - 6
R = 8
Answer(s): (a) 3; (b) 8
