(a)
Since 4 in the hundreds place is not enough to subtract 6, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 9.
H - 1 - 2 = 6
1 + 2 + 6 =
9H =
9(b)
Since 4 in the hundreds place is not enough to subtract 6, 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 6.
10 + 4 -
J = 6
14 - 6 =
8J =
8 Answer(s): (a) 9; (b) 8
