Hi everyone,

I have not posted a wrap for a few days.  I have been preoccupied I am sorry.  


There have been many great questions and most of these were answered very well by Tetration, CPhill, ororen1909, NotTheBestMathMaster, rajaae, Kitty<3, Alan, and geno3141.  Thanks all

Every maths mover must be able to find something interesting in there.  


1) Interesting domain question.

3) What are permutations and combinations ?      Melody

4) A really good rates and volume question.        Melody

5) Physics    Thanks Alan

7) All in fun :))    NotTheBestMathMaster, Melody, Nauseated, Alan and CPhil.

8) Formula for triangular numbers  Thanks Alan and Chris

9) Parabola question, different from the norm - Thanks Alan

Answering some of those questions you posted yesterday sent me scurrying back to refresh my memory too, JayyH  !!!!

But that's's always good to review things.....

Here's a couple that I used.....

If it's any consolation...I always found this topic a little difficult, as well!!!
