About DecimalHero — Quick Math Practice

DecimalHero Quick Math is a popup practice tool for homework. Click the toolbar icon to get a short percent, fraction, rounding, or decimal question. Check your answer instantly and keep a local streak. Switch to Tools for percent of a number, percent change, fraction-to-decimal, decimal-to-fraction, and rounding to decimal places or significant figures. Type dh in the Chrome address bar, then press Tab, to jump to DecimalHero practice pages. Everything runs on your device. The extension does not read the pages you visit and does not collect accounts, names, or browsing history. Optional streak data stays in Chrome local storage on this computer. Want longer practice sessions with step-by-step help? Open decimalhero.com.
