(a)
Since 7 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 6.
F - 1 - 2 = 3
1 + 2 + 3 =
6F =
6(b)
Since 7 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 7 so that the sum 17 can be used to subtract 9.
10 + 7 -
G = 9
17 - 9 =
8G =
8 Answer(s): (a) 6; (b) 8
