Mental Math Practice for Trading Interviews
No-calculator arithmetic against the clock - the classic trading-firm speed test.
Free account required to play.
Trading firms open their process with a raw speed test: fast, no-calculator arithmetic across integers, fractions, decimals, and percentages. The timed screens used across market making all probe the same thing - can you compute accurately when the clock is running and the pressure is on.
The Mental Math Blitz recreates that format. Questions come one after another, correct answers auto-advance so a good run flows, and your score reflects how many you clear inside the time limit. The goal is to make arithmetic automatic, so that in a real interview your working memory is free for the actual problem.
What it's modelled on
The timed mental-arithmetic screens market makers filter on
This mirrors the first-round numerical filter at speed-focused market makers - commonly reported as dozens of arithmetic questions in a handful of minutes, with a penalty for errors. Like those assessments, it's no-calculator and correct answers auto-advance under a hard time limit.
