Pretty basic, but easy to "ship", if you can live without paper. Your
local library probably has paper ones.

Thanks for posting the first site, my kid is about to ask me trig.
questions soon and at first sight looks like a great place. Was
thinking of winging it to see how much I remember.

Lately, the estimate multiplied by an estimate divided by an estimate
equals a rounded answer questions are driving me crazy. And then
compare over time when your generalizing doesn't make since to me. Why
not use the exact numbers to make sure it all ads up. I use to get in
trouble at the black board for doing a lot of the equation in my head.
Like being marked for being the one who stole the teachers book. It
wasn't me, but I heard rumor that it was out and about. That's how the
Socialites passed the class.
