Best features
Fast practice with useful feedback.
Mental Math is a student-facing helper app: simple to open, responsive on desktop and mobile, and designed to make repeated practice practical.
Keyboard + math keypad input
Students can type answers directly or use the on-screen keypad, with answer normalization and immediate correct/wrong validation.
Daily and short practice modes
Use 20-question Daily Practice or focused 5-question batches, with a saved starting level/page for convenient continuation.
Progress + repeat logic
Local progress statistics and the default 80% passing-rate repeat logic help students revisit practice that still needs reinforcement.
Improved math expression display
Fractions, mixed numbers, exponents, square roots, cube roots, and nth roots are typeset for clearer mathematical reading while answer input stays simple.
Printable workbook output
Create printable worksheets and practice pages with continuous answer keys. Optional cover pages and print-friendly layouts support offline study.
