Terms of use

Effective October 29, 2026. Updated November 9, 2026.

math.wiki is run by NUDGELEARN LLC, 9 Van Riper Ave, Montville, NJ 07045, USA ("we"). By using math.wiki you agree to these terms. Questions: support@math.wiki.

Lessons

The lessons on math.wiki are free to read, for anyone. You may link to them and use them in your teaching. Please do not copy the site wholesale or republish lessons as your own.

Accounts

Teacher accounts are for adults. Keep access to your email or sign-in provider secure, because anyone who controls it can sign in as you. One account is for one person; do not share it.

Worksheets, quizzes, tests and keys

Sheets you download with an account or plan are licensed to you, the person named on the sheet, for use with your own students. You may print them, copy them for your classes, and post them in your own class's private space (for example a learning management system your students sign into). You may not:

• post them where the public can reach them, including websites, file-sharing sites and marketplaces;
• sell them or give them to other teachers or schools;
• remove the license line printed on them.

We may suspend an account whose sheets are being shared publicly.

Plans and payment

Paid plans, their prices and their monthly limits are shown where you buy them. Monthly limits reset on the 1st of each month (New York time); unused items do not carry over. Subscriptions renew automatically until you cancel. When you cancel, your plan keeps working until the end of the period you paid for. Sheets you downloaded while your plan was active stay licensed to you, on these same terms, after it ends. We do not refund partial periods, except where the law requires it. A course pass is a one-time purchase for the sheets in that course. If we change a price, the change applies from your next renewal, and we will tell you before it does.

Accuracy

We work to make lessons and answer keys correct, but mistakes happen. Please check materials before you use them for grades, and tell us about any error at support@math.wiki. math.wiki is provided "as is", without warranties of any kind.

Limits on liability

To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability to you is limited to what you paid us in the 12 months before the claim.

Ending

You can stop using math.wiki and ask us to delete your account at any time. We may end or suspend accounts that break these terms.

Law

These terms are governed by the laws of New Jersey, USA.

Changes

If we change these terms we will update the date at the top. If a change matters to account holders, we will also email them.

Our privacy policy explains what we collect and why.
