Give kids, students, and parents a website that can be used safely in school while providing educational content that the kids will actually enjoy!
While we wish that could make Mathmoo.com complete ad free, we wouldn’t be able to keep it online for very long. Hosting of this website can very expensive and the only way to pay for that is either to charge users directly (which we really want to avoid so we can reach as many kids as possible!) or use advertisements.
Ads give us the money to support the small team of people working on the site (While we would love to do this for free, we need a little bit of money to put food on the table). More money also gives us the option to keep creating great educational material and expanding to give even more value to the users of our site which is our ultimate goal.
