Last semester I learned many things. Unfortunately, because of winter break i don't remember all of them. Their is one thing that stuck with me. Integers,  adding, subtracting, dividing, and multiplying them. I think this stuck with me because i struggled with integers. Mostly subtracting and adding, I had to really try better than my best to comprehend how to subtract really simple integers. I now get half of what the teacher talks about when the teacher talks about integers. That's a huge accomplishment for me, since i didn't get it at all when we started. 
                             One thing I remember about integers is if your subtracting form a integer technically your adding negative. I don't how to explain but that's what my teacher said. It really sunk in.
