Find the missing digits.
- H
- K
H456 - 18K2 = 7594(a)
In the hundreds place, 4 is less than 8.
So, there is regrouping in the thousands place.
H - 1 - 1 = 7
H = 7 + 1 + 1
H = 9
(b)
In the ones place, 6 is more than 2.
So, there is no regrouping in the tens place.
5 - K = 9
In the tens place, 9 is more than 5.
This means that there is a regrouping done in the hundreds place so that 15 can substract a certain number to get 9.
K = 15 - 9
K = 6
Answer(s): (a) 9; (b) 6
