Find the missing digits.
- L
- N
L517 - 82N1 = 1246(a)
In the hundreds place, 5 is more than 2.
So, there is no regrouping in the thousands place.
L - 8 = 1
L = 1 + 8
L = 9
(b)
In the ones place, 7 is more than 1.
So, there is no regrouping in the tens place.
1 - N = 4
In the tens place, 4 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 4.
N = 11 - 4
N = 7
Answer(s): (a) 9; (b) 7
