Really easy!!! Take it step by step. How I learned it is by something called PEMDAS. P stands for Parentheses and that means that if there are any numbers in any parentheses than you do whatever operation it says to do inside the parentheses. Next comes E for exponents. You can look up what it means but in this case you don't need it because it's not in this problem. Now M comes in for multiplication. So the third step is to multiply any multiplication problem in the question. D is for division so you divide anything there is to divide in the question. Now A for addition. Add anything you need to add and the last step is to subtract anything . So the answer to that problem is 71. U should check just in case. I hope I was a big help!
