A1 ing~

I got a 236 quiz on Monday, a mat223 quiz on Tuesday and a csc207 quiz on Wednesday. So I just started A1 this morning.For question #1, i find out we might use the summation notations. I googled it. It's kind of review of high school math. There are some formulas i feel they might be useful in the future. Here is the link. http://en.wikipedia.org/wiki/Summation
