Solve arithmetic problems as fast as you can. Choose the correct answer. 60 seconds, as many as possible. Tests numerical processing speed and mental arithmetic.
Mental arithmetic speed is a strong predictor of mathematical achievement and is heavily featured in standardized testing. It reflects the automaticity of number facts stored in long-term memory and the efficiency of numerical working memory. Arithmetic speed is a practical human benchmark tested in everything from job assessments to standardized exams.
Pair this with the Processing Speed Test and Mini IQ Test for a reasoning profile.

Mental arithmetic speed reflects how automatically number facts have been encoded in long-term memory. When basic operations become automatic - when you don't need to consciously calculate 7 ร 8, because the answer "56" retrieves instantly - working memory is freed up for higher-level mathematical reasoning. This is why children who master arithmetic facts outperform those who don't on algebra and problem-solving, even when given the same instruction time.
Our test spans three difficulty levels: Easy (addition and subtraction with small numbers), Medium (multiplication and division), and Hard (mixed operations with larger numbers). Performance on harder arithmetic strongly correlates with working memory capacity - because multi-step mental calculations require holding intermediate results while performing further operations, exactly what working memory is for.
Daily mental arithmetic practice - even 10 minutes - measurably improves numerical fluency within weeks. Combine with Processing Speed and Mini IQ Test for a complete quantitative cognition profile.
On the Medium difficulty in 60 seconds, more than 40 correct answers is exceptional numerical fluency, while 25-40 correct is strong and above average.
When basic number facts are automatic, working memory is freed up for higher-level reasoning, which is why children who master arithmetic facts outperform others on algebra even with the same instruction time.
Yes. Daily mental arithmetic practice, even just 10 minutes, measurably improves numerical fluency within a few weeks by strengthening automatic retrieval of number facts.
It reflects arithmetic fluency and automaticity more than deep mathematical reasoning, so a strong score shows fast recall of basic operations rather than advanced problem-solving skill.
Speed and accuracy compete for the same limited attentional resources, so pushing for faster answers under time pressure naturally increases the chance of small calculation errors.
Yes, regular practice with basic arithmetic builds faster fact retrieval and pattern recognition, similar to how typing speed improves with consistent practice.
Processing speed for simple arithmetic can gradually decline with age, though experienced individuals often compensate with more efficient calculation strategies built from decades of practice.
It's largely measuring memorized arithmetic facts, especially for smaller numbers, since fast recall of number facts is faster than working through calculation steps each time.
Some researchers suggest reduced daily mental arithmetic practice due to calculator reliance may lead to slower manual calculation speed, though formal evidence on long-term effects is limited.
Hard mode mixes operations with larger numbers, requiring you to hold intermediate results in working memory while performing further calculations, which strongly correlates with overall working memory capacity.
