This past week we did a lot of stuff with aleks. It is really helping me alot. If you do not understand something all you have to do is click explain and it explains it to you. It has helped me a lot with like, simple math and stuff. The only thing i do not like is that it kind of like stalks you because it can tell if you click on another tab and stuff. And it is soooo many problems. But other than that, it is pretty helpful. This week we also learned about vectors. They represent motion. If you are adding vectors you add them from head to tail, but if you are adding them algebraically, you add the components. The triangle that you get after you add the vectors from head to tail is the result of what you added. They have a magnitude and a direction. I can not relaly do any examples because its all drawing graphs and such.
