Question

Steps to solving this: If A+A=30, B+B=20, C+C =8, What is A+BXC? I get confused on when to add, subtract, multiply and divide. I am 71 years old, and it's easy to confuse me. Do you have the formula for what always goes first when doing an addition, subtraction, multiplication and division problem or any part of it? Does it matter if parts of the equation is in parenthesis? I really get confused with this. Any help would be appreciated.
