We use cookies to offer you a better browsing experience, analyze site traffic, and personalize content. Read about how we use cookies and how you can control them in our Privacy Policy. If you continue to use this site, you consent to our use of cookies.

WHY. We are a small, independent publisher founded by a math teacher and his wife. We believe in the value we bring to teachers and schools, and we want to keep doing it. We keep our prices low so all teachers and schools can benefit from our products and services. We ask that you help us in our mission by reading and following these rules and those in our Single User License Agreement.

When you use this site, you are agreeing to comply with these Terms & Conditions and our Single User License Agreement.

PLEASE, NO SHARING. We know it’s nice to share, but please don’t share your membership content or your login or validation info. Your membership is a Single User License, which means it gives one person – you — the right to access the membership content (Answer Keys, editable lesson files, pdfs, etc.) but is not meant to be shared.

Please do not copy or share the Answer Keys or other membership content.

Answer keys are for teacher use only and may not be distributed to students.

Please do not post the Answer Keys or other membership content on a website for others to view. This includes school websites and teacher pages on school websites.

You can make in-house photocopies of downloaded material to distribute to your class. You may not pay any third party to copy and or bind downloaded content. You may not send out downloaded content to any third party, including BOCES districts, to copy and or bind downloaded content. You may not publish or compile downloaded content into the digital equivalent of a bound book.

You may distribute downloaded content digitally to your class only through password protection or enclosed environments such as Google Classroom or Microsoft Teams.

If you are a school, please purchase a license for each teacher/user.

PLEASE RESPECT OUR COPYRIGHT AND TRADE SECRETS. We own the copyright in all the materials we create, and we license certain copyrights in software we use to run our site, manage credentials and create our materials; some of this copyrighted software may be embedded in the materials you download. When you subscribe, we give you permission (a “Single User License”) to use our copyrights and trade secrets and those we license from others, according to our Terms & Conditions. So in addition to agreeing not to copy or share, we ask you:

Please don’t reverse-engineer the software or printed materials. This includes copying or binding of downloaded material, on paper or digitally.

Please don’t change or delete any authorship, copyright mark, version, property or other metadata.

Please don’t try to hack our validation system, or ask anyone else to try to get around it.

Please don’t put the software, your login information or any of our materials on a network where people other than you can access it.

Please don’t copy or modify the software or membership content in any way unless you have purchased editable files.

If you create a modified assignment using a purchased editable file, please credit us as follows on all assignment and answer key pages:

FEEDBACK REQUESTED. We value your feedback about our products and services. We think others will value it, too. That’s why we may do the following (and we ask that you agree):

Use your feedback to make improvements to our products and services and even launch new products and services, with the understanding that you will not be paid or own any part of the new or improved products and services (unless we otherwise agree in writing ahead of time).

Share your feedback, including testimonials, on our website or other advertising and promotional materials, with the understanding that you will not be paid or own any part of the advertising or promotional materials (unless we otherwise agree in writing ahead of time).

SATISFACTION GUARANTEED. If you are not 100% satisfied, we will refund you the purchase price you paid within 30 days. To get a refund:

Within 30 days of your purchase,

TECHNICAL SUPPORT: If you are having trouble logging in or accessing your materials, or if your downloaded materials won’t open or are illegible, please notify us immediately by email at [email protected] so we can get it fixed.

NO WARRANTY. We believe in the quality and value of our products and services, and we work hard to make sure they work well and are free of bugs. But that said, we are providing our products and services to you “as is,” which means we are not responsible if something bad happens to you or your computer system as a result of using our products and services. For our full Disclaimer of Warranties, please see our Single User License Agreement Here.

DISPUTES. If we have a dispute that we cannot resolve on our own, we will use mediation before filing a lawsuit in a regular court (except that we can use small claims court). Mediation means we will each present our case to one or more professional mediators who are chosen and paid by all parties to the dispute, and the mediator(s) will work with us to find a fair resolution of our dispute. Mediation is a faster and less formal way of resolving disputes and therefore tends to cost less.

If you have a dispute, please send a letter requesting dispute resolution and describing your claim to:

Emath Instruction Inc.
10 Fruit Bud Lane
Red Hook, NY 12571

LIMITATION OF LIABILITY. If you do win a case against us, the most you can recover from us is the amount you have paid us.
