(a)
Add 5 and 6 in the ones place and take the digit in the ones place from the answer.
5 + 6 = 1
1 M =
1(b)
Since 5 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 5 so that the sum 15 can be used to subtract 9.
10 + 5 -
N = 9
15 - 9 =
6N =
6 Answer(s): (a) 1; (b) 6
