memorizing numbers spoken aloud.
10 rounds with increasing difficulty.
How to Play
- Press "Start" and a countdown begins.
- A math problem appears. Type the answer and press Enter.
- Simultaneously, numbers are spoken aloud. Listen and memorize them while solving math.
- After submitting math (or time expires), type the numbers you heard in order.
- Phase 1 (R1-3): Simple addition + 3 digits
Phase 2 (R4-6): Add/subtract + 4 digits
Phase 3 (R7-8): Multiplication + 5 digits
Phase 4 (R9-10): Hard multiplication + 6 digits - After all 10 rounds, your score is calculated from math and memory accuracy.

About the Multitask Test
The Multitask Test measures "Divided Attention" — the ability to process multiple tasks simultaneously. This test combines a visual-motor task (reading and typing math answers) with an auditory-memory task (listening to and remembering spoken numbers).
The Science of Divided Attention
The brain's attention resources are limited. Processing visual information (reading math, typing answers) and auditory information (hearing numbers, memorizing them) simultaneously causes performance to decline in both areas — known as "Dual-Task Interference." The prefrontal cortex manages attention allocation, switching resources between the two tasks.
Tips to Improve
- Solve math quickly: Spending too long on math means less attention for number memory.
- Mentally rehearse the numbers: Silently repeating heard numbers helps retention.
- Find a rhythm: Get used to the number spacing and develop a listen-rehearse-calculate rhythm.
- Practice regularly: As math becomes automatic, more attention can be devoted to memory.
FAQ
Q. I can't hear the audio
A. This test uses the browser's Speech Synthesis API. Make sure your volume is up and your browser supports speech synthesis. If unavailable, numbers will be shown on screen instead.

Q. Should I prioritize math or memory?
A. Balance is key. Math is worth 1 point per problem, while memory is 1 point per digit — so memory has a larger total weight. Solving math quickly and focusing on memory is the best strategy.

Q. What's an average score?
A. First-timers typically score 40-60%. With practice, 70%+ is achievable as math solving becomes more automatic.
