As long as you don't say anything stupid you get all points... there's no real measurements of deduction on this
I don't see how anyone can get this wrong... even if it is wrong I can't verify it.
2pts for every equation you get right. It's all or nothing for the 2 pts.
The 2*a should be in parenthesis, all or nothing.
Basically 2pts for each you point out. All or nothing for the 2pts.
3 pts each, all or nothing for the 3pts.
All or nothing. I will excuse any really stupid mistakes (according to my judgement).
I'm a bit easy this time, badly formated output won't get you any points off... but if you have unreadable output you get all points off. All or nothing.
It's all or nothing. If your program is hard to read then I'm taking off all points, else it's all good.
No comments in the body of the program: -8pt. Others are tolerable.
