[quote=Anonymous][quote=Anonymous]It's PEMDAS and the answer is 10. 3^3 - 6(10-8) +5 Parentheses: (10-8) = 2 Exponent: 3^3 = 27 Multiplication: 6 * 2 = 12 Division: N/A [b]Addition: 12 (it's subtraction not negative 12) + 5 = 17 Subtration: 27 -17[/b] Answer: 10 [/quote] It's not PEMDAS, though. It's parentheses, exponents, multiplication/division from left to right, addition/subtraction from left to right. Parentheses: (10-8) = 2 Exponent: 3^3 = 27 Multiplication: 6*2 = 12 Addition/subtraction, from left to right: 27 - 12 + 5 = 15 + 5 = 20[/quote]
