## What is Harumath?

Harumath is a timed mental math trainer for people who need to be fast and accurate under pressure — quant and trading interview candidates, numerical reasoning and GRE test takers, and anyone rebuilding arithmetic speed.

Sprint through addition, subtraction, multiplication, and division against the clock, then review your accuracy, pace, and combo flow to see exactly where you slow down.

- 90-second daily sprint — the classic timed arithmetic format
- Speed, accuracy, multiplication, comparison, mixed, and deep-focus modes
- Progress review for rhythm, accuracy, combos, and level flow
- Missed-problem review and weak-spot cards so you drill what you got wrong
- Shareable daily result card to keep a streak with friends
- Visual math puzzles: number maze, 24 game, and magic square
