On my pre-test, I did not know a lot of the math sentences and the order of operations, but when I did the post-test I knew a lot about the order of operations and math sentences. Now that I know about P.E.M.D.A.S, I know when to put in parentheses and to do parentheses first and then do exponents then do division and multiplication at the same time. Then, do addition. Then do addition.

Here are some pictures of questions I got right on my post-test and got wrong on my pre-test.
