In helping my daughter with her third grade math I realized I have forgotten how to do algebra. (Not that she was doing algebra, I just suddeny realized as I was reducing fractions that I had forgotten A LOT and I wouldn't be able to isolate X for money.)

I know there are smart ladies, homeschooling moms, and fabulous teachers on the forum. Any recommendations for a math book that will refresh my skills? Say from basics through, I dunno, trig?
