## Brushing up/learning more

I'm very interested in not only brushing up, but learning as well. I have not done any mathematics for quite some time, over 4 years, and the highest course I took was College Algebra. Where do you suggest I start? By the way, this is my first experience in Wikiversity, so please forgive me if this is not the correct place to ask such a question. Thank you, Rogerh 19:23, 23 January 2008 (UTC)

Hello Roger, well that certainly depends on e.g. what you still remember and what you liked in maths. One way could be - without knowing much of your situation/preferences - that you look around (e.g. at the Wikiversity:School_of_Mathematics#Divisions_and_departments) and dig deeper. It also could help, if you talk to some of the participants there. And if you miss something you can optimize the content, we are a wiki. ----Erkan Yilmaz (Wikiversity:Chat, wiki blog) 19:43, 23 January 2008 (UTC)
If you're like me, you'll like to solve story problems more than purely abstract math problems. For example, here's one to help you brush up on algebra:
"When Phil was 13 years old, Jill was five times as old as Bill. When Phil was twice as old as Bill, Jill was 19. The total of their three ages now is 100 years. How old is each now ?" StuRat 14:10, 24 January 2008 (UTC)

The answer is that Phil is 38 Jill is 35 and Bill is 27 Ricky Di Don (discusscontribs) 21:03, 16 October 2016 (UTC)

## Just want to ask a question

If there are twenty-five people in a room and everyone shakes hands with everyone else once, how many handshakes are there? (I got three hundred but my textbook says three hundred and twenty-five which I think is wrong. If you also got any of these two answers please tell me and explain how.)

See http://www.mathcircles.org/node/835 for the solution to this problem. -- Dave Braunschweig (discusscontribs) 03:35, 17 October 2016 (UTC)

I have an home it says

```Determine the gradient between the given coordinates:
```
