7x7 = 49
7x5 = 35
7x3 = 21
7x1 = 7
7x0 = 0
don't need to do 5x7 because we already did 7x5
5x5 = 25
5x3 = 15
5x1 = 5
don't need to do 3x7 because we already did 3x7
don't need to do 3x5 because we already did 3x5
don't need to do 5x0 because we already did 7x0
3x3 = 9
3x 1 = 3
don't need to do 3x0 because we already did 7x0
don't need to do 1x7 because we already did 7x1
don't need to do 1x5 because we already did 5x1
don't need to do 1x3 because we already did 3x1
don't need to do 1x0 because we already did 1x0
counting all the different answers we got, the total number of POSITIVE combinations is:
zero can't be negative but if we'd multiplied each of the other 10 by a negative value we would have got another unique value (for instance 1x -1 = -1
so we add 10 more to the count of possible combinations
11+10 = 21 possible combinations
