Find the missing digits.
- S
- T
S513 - 74T2 = 2081(a)
In the hundreds place, 5 is more than 4.
So, there is no regrouping in the thousands place.
S - 7 = 2
S = 2 + 7
S = 9
(b)
In the ones place, 3 is more than 2.
So, there is no regrouping in the tens place.
1 - T = 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.
T = 11 - 8
T = 3
Answer(s): (a) 9; (b) 3
