Find the missing digits.
- S
- T
S965 - 27T1 = 1174(a)
In the hundreds place, 9 is more than 7.
So, there is no regrouping in the thousands place.
S - 2 = 1
S = 1 + 2
S = 3
(b)
In the ones place, 5 is more than 1.
So, there is no regrouping in the tens place.
6 - T = 7
In the tens place, 7 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 7.
T = 16 - 7
T = 9
Answer(s): (a) 3; (b) 9
