Find the missing digits.
- P
- R
P314 - 35R1 = 1773(a)
In the hundreds place, 3 is less than 5.
So, there is regrouping in the thousands place.
P - 1 - 3 = 1
P = 1 + 3 + 1
P = 5
(b)
In the ones place, 4 is more than 1.
So, there is no regrouping in the tens place.
1 - R = 7
In the tens place, 7 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 7.
R = 11 - 7
R = 4
Answer(s): (a) 5; (b) 4
