Hello. I kind of forgot about this, and so I shall be doing it late. I was assigned questions 12, and if you already know, it includes a lot of addition and subtraction. Here's what the question looks like. Anyways, the questions will be placed in the slide below, as it's easier to read as opposed to a long post.
Comment on mistakes, or if anything is misunderstood. Also comment if you just wanted to say good job. (: Keep up the good work 9-05!
