DAY 66:

Today’s Challenge

Multiply two numbers together and then add or subtract a third number to reach the target answer of 60. The three numbers used in each calculation must all be digits from 1-9 and in this challenge they can be repeated.

As an example, one way of making 60 is (9×6)+6, can you find the other THREE ways?

[Note:  (9×6)+6 and (6×9)+6 counts as the same way.]
