Here you’ll find free articles and free textbooks on high-school and college mathematics, written by Stan Brown. You’ll also find articles on other interesting subjects, and some free utility software.
Enjoy, and let me know what you think!
I pay the hosting costs for BrownMath.com out of pocket. If this site is useful to you, please consider making a donation.
It’s always okay to link to any page in this site, or to print a page for your own personal use.
If you want to copy any material for any purpose, please respect the amount of work I’ve put into these pages and ask permission at the email address below.
I get many requests from people wanting me to sell them link space, or wanting to pay me to place an article of theirs on BrownMath.com. I have never done that, and I never will.
You’ll see an occasional text link, like the one at the bottom of this page, inviting you to donate a few bucks to help with operating expenses, if you find this site’s information useful. There are no banner ads or click-through ads and no sneaky one-pixel pictures. Nothing is behind a paywall.
I link to other sites that are relevant to my topics, especially if they explain something that I don’t. I don’t link to pages behind paywalls, except for the purpose of documenting a source I drew from.
If you have a link that matches those criteria, please tell me about it. Please explain briefly what’s at the link and—if it’s not obvious—what on my site it’s relevant to. I’ll only investigate a link if you give me a reason to.
