DAY 161

Today’s Challenge

Here is a number puzzle where THREE UNIQUE digits from 1-9 must be used in a particular way to arrive at a specified target number.

The rule is to multiply two numbers together, then either add or subtract the third number, so you arrive at the target number 30.

As an example, one such way of making 30 is (8×3)+6. Can you find the other FOUR ways of making 30?

[Note:  (8×3)+6 = 30  and  (3×8)+6 = 30  counts as just ONE way]
