Mental Math Duel is a mental arithmetic trainer that helps you practice addition, subtraction, multiplication, and division in your head — no calculator needed.
The app offers three modes:
Quick Fire — answer as many questions as you can within 60 seconds. Questions get harder as your score increases.
Survival — you have 3 lives. Each wrong answer costs one life. See how many questions you can answer correctly before running out.
Daily Challenge — a fixed set of 20 questions. Complete them and track your accuracy and score each time you play.
A streak system rewards consecutive correct answers with bonus points. Accuracy percentage and best streak are shown at the end of each session.
The difficulty adjusts based on your performance — starting with simple addition and subtraction, then introducing multiplication and division as you progress.
No account needed. No internet connection required. All data stays on your device.
