Find the missing digits.
- Y
- Z
Y568 - 12Z5 = 6293(a)
In the hundreds place, 5 is more than 2.
So, there is no regrouping in the thousands place.
Y - 1 = 6
Y = 6 + 1
Y = 7
(b)
In the ones place, 8 is more than 5.
So, there is no regrouping in the tens place.
6 - Z = 9
In the tens place, 9 is more than 6.
This means that there is a regrouping done in the hundreds place so that 16 can substract a certain number to get 9.
Z = 16 - 9
Z = 7
Answer(s): (a) 7; (b) 7
