(a)
Since 2 in the hundreds place is not enough to subtract 8, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 7.
F - 1 - 5 = 1
1 + 5 + 1 =
7F =
7(b)
Since 2 in the hundreds place is not enough to subtract 8, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 2 so that the sum 12 can be used to subtract 8.
10 + 2 -
G = 8
12 - 8 =
4G =
4 Answer(s): (a) 7; (b) 4
