Question

M stands for a whole number greater than 10 and less 20

n stands for a whole number greater than 2 an less than 10

what is the smallest number that m*n could be?
what is the largest number that m-n could be?

Answer 1

Less: M=11 N=3

Since M has to be greater than 10, but less than twenty, the smallest number it could be would be 11. The same goes for 3.

More: M=19 N=9

It has to be less than 20, so M cannot be 20. N also has to be less than 10.

Answer 2

The smallest number that m*n could be is 33 because the smallest m stands for 11 and the smallest n stands for 3, so 11*3=33.

The largest number that m-n could be is 16 because the largest m stands for 19 and the smallest n stands for 3, so 19-3=16
