I'm in the defense industry. Spent the last 15 years in the engineering side of the house.There is an order of precedence in algebra. The order is PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition and Subtraction (from left to right). The answer is 120.
I always tell my kids, "Math is important...that's why I have people that do it for me."
