I Need To Solve This Equation...
(You Can Only Use Each Sign ONCE, And You Are Aloud To Use Brackets)
Plus, Minus, Divide, Multiply (Have To Use All Four - And Only Once!!)
7 (?) 5 (?) 4 (?) 7 (?) 6 = Fifteen
I Got The Right Answer - But, That Was With Using The Same Sign Three Times...
Thank You!!

Note To A Few Of You...
It Will Only Work IF You Have The Brackets Around The 7 & 5... Or Else, You Will End Up With:
9.75

Note: there are only 24 combinations of signs that you would have to try... but you already have your answer:
(7 + 5) / 4 * 7 - 16 = 15

7+5=12
12/4=3
3*7=21
21-6=15
so:
(((7+5)/4)*7)-6=15
