Advanced Mathematics: an Incremental Development – problem set 5, #10

 * 1. $$\frac{y^{x+3} y(\frac{x}{2}-1)z^a}{y(\frac{x-a}{2})z(\frac{x-a}{3})}$$

Turns out all my work was wrong. At least I learned a good chunk of the math syntax.

Percents

 * 1. $$.2x = 60.6$$


 * 2. $$x = \frac{60.6}{.2}$$


 * 3. $$x = 303$$

Simple, I know. I just can't do that in my head all the time. Sometimes it just doesn't click.
