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.
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 × 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.
