Step-by-step Explanation: The first thing you need to do is know what order to go in, for example ‘pemdas’. (Parentheses, exponents, multiplication, division, additions, and subtraction.) The first step is going to be the parenthesis so, 8 + 7 = 15. The second step is going to be to distribute, which is multiplication so, 12 x 15 = 180. The last step is to make sure you went through ‘pemdas’ all of the way.
