Find the missing digits.
- N
- P
N315 - 41P3 = 4152(a)
In the hundreds place, 3 is more than 1.
So, there is no regrouping in the thousands place.
N - 4 = 4
N = 4 + 4
N = 8
(b)
In the ones place, 5 is more than 3.
So, there is no regrouping in the tens place.
1 - P = 5
In the tens place, 5 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 5.
P = 11 - 5
P = 6
Answer(s): (a) 8; (b) 6
