(a)
Since 4 in the hundreds place is not enough to subtract 7, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 9.
Y - 1 - 5 = 3
1 + 5 + 3 =
9Y =
9(b)
Since 4 in the hundreds place is not enough to subtract 7, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 4 so that the sum 14 can be used to subtract 7.
10 + 4 -
Z = 7
14 - 7 =
7Z =
7 Answer(s): (a) 9; (b) 7
