DAY 224

Today’s Challenge

Three UNIQUE digits must be used to arrive at the target number 37.

The rule – players must multiply two numbers together, then either add or subtract the third number to achieve the target answer of 37.

Using the formula (a×b)±c, where a, b and c are three unique digits from 1-9, one way of achieving 37 is (7×5)+2, can you find the other SEVEN ways?

[Note:  (7×5)+2 = 37 and  (5×7)+2 = 37 counts as just ONE way.]
