1. simplify 9 x 5 + 2 / 8 - 3 by the way " / " means division.

Your answer will be 46. Remember PEMDAS. Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. These are the steps you would do a problem like this in. First you would multiply 9x5, because there is no parentheses or exponents. Next, divide. This will leave you with 45+4-3. Next, do your addition and subtraction. There's your answer Hope this helps  :)

The answer would be 42.25 because first you multiply 9 and 5, then divide 2 and 8 and add that to 45, then you subtract 3 from that.
