Cancellation/ simplification error sample

 * $$\frac{2\times (x + 2)}{2}=\frac{2}{2}\times \frac{x+2}{1}=1 \times \frac{x+2}{1}=x+2$$,

I think, this would be simpler to understand, if it was:
 * $$\frac{2\times (x + 2)}{2}=\frac{1}{2} \times 2 \times (x+2)=1 \times (x+2)=x+2$$,

Interval notation
I suggest the sequence of interval notations of the first table match that of the second table. So, the first table would read down, [],, [), (], rather than, at present, , [), (], []. Whether that change is agreed to or not, I would not change the sequence of the second table. Regards, Max

What is needed?
This section is listed as being far from completion. I, however, am not sure what to contribute. What does this section need?--Weux082690 (discuss • contribs) 14:35, 2 May 2013 (UTC)
 * I allocated 8 hours to try to develop this section more fully. I spent some of the time more fully developing the subsection on exponents and radicals. There was no discussion at all about logarithms, so I spent the rest of the time developing that. I don't believe there are any major topics in algebra appropriate for a pre-calculus review that remain to be covered, although I could certainly be wrong about that. I think that there is a lot more work still to be done, though, in organizing and clarifying the material and adding examples and exercises. --Greenbreen (discuss • contribs) 04:32, 21 March 2017 (UTC)
