(a)
Since 6 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 5.
N - 1 - 2 = 2
1 + 2 + 2 =
5N =
5(b)
Since 6 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 6 so that the sum 16 can be used to subtract 7.
10 + 6 -
P = 7
16 - 7 =
9P =
9 Answer(s): (a) 5; (b) 9
