Find the missing digits.
- Y
- Z
Y514 - 28Z1 = 4683(a)
In the hundreds place, 5 is less than 8.
So, there is regrouping in the thousands place.
Y - 1 - 2 = 4
Y = 4 + 2 + 1
Y = 7
(b)
In the ones place, 4 is more than 1.
So, there is no regrouping in the tens place.
1 - Z = 8
In the tens place, 8 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 8.
Z = 11 - 8
Z = 3
Answer(s): (a) 7; (b) 3
