Use the numbers 7,5,6 and 3, each only once, to create an expression that equals 75. You may use addition, subtraction, multiplication, and division, but you must use parentheses

Respuesta :

(7 + 5) x 6 +3

I don't include the "=75" because that would make it an equation and they only asked for an expression.

Check:  7+5=12
             12x6 = 72
              72+3 = 75  Success!
