Advertising Disclosure

Project Math may earn money from display ads, affiliate links, or sponsorships. Any paid relationship should be disclosed clearly near the relevant content.

Last updated: September 9, 2026.

Display ads

Project Math may display ads through Google AdSense or another ad network. Ads help keep calculators free, but ad placement should not block calculator inputs, hide results, or imitate download buttons, navigation, or site controls.

Affiliate links

Some future product or material links may be affiliate links. If you click one and buy something, Project Math may earn a commission at no extra cost to you.

Editorial independence

Calculator formulas, shopping-list logic, and project warnings should be written for usefulness first. Paid relationships should not change the math or remove safety caveats.
