Find the missing digits.
- Z
- A
Z918 - 36A1 = 1237(a)
In the hundreds place, 9 is more than 6.
So, there is no regrouping in the thousands place.
Z - 3 = 1
Z = 1 + 3
Z = 4
(b)
In the ones place, 8 is more than 1.
So, there is no regrouping in the tens place.
1 - A = 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.
A = 11 - 3
A = 8
Answer(s): (a) 4; (b) 8
