Find the missing digits.
- S
- T
S147 - 47T1 = 1386(a)
In the hundreds place, 1 is less than 7.
So, there is regrouping in the thousands place.
S - 1 - 4 = 1
S = 1 + 4 + 1
S = 6
(b)
In the ones place, 7 is more than 1.
So, there is no regrouping in the tens place.
4 - T = 8
In the tens place, 8 is more than 4.
This means that there is a regrouping done in the hundreds place so that 14 can substract a certain number to get 8.
T = 14 - 8
T = 6
Answer(s): (a) 6; (b) 6
