Quick Maths Assessment
10 questions. 5 seconds each. Pick the correct answer before time runs out. Calculators are a disciplinary matter.
Ten questions. No calculator. No spreadsheet to quietly check your work in. Just you, basic arithmetic, and the slow realisation that you've forgotten how subtraction works.
Mental arithmetic without a calculator is a genuinely different cognitive task from arithmetic with one — it leans on working memory (holding numbers in your head while operating on them) rather than just procedural recall, which is part of why it tends to feel disproportionately hard the moment you're under time pressure. It's also one of the more practiced cognitive skills in everyday life without anyone calling it that: splitting a bill, estimating a discount, sanity-checking a spreadsheet before you trust it. Ten questions here, scored on speed and accuracy together, is a quick honest read on how that skill is holding up today — no judgement either way.
Answer ten quick maths questions as accurately and quickly as you can. Type or click your answer and move straight to the next one — there's no going back.
Each correct answer earns points up to 1000 total, with faster answers worth more. Wrong answers earn nothing, so don't guess wildly.
It's the most legitimate-looking thing on this entire site if your boss glances at your screen. Genuinely defensible as 'mental maths practice.'
Is there a time limit per question?
No hard limit, but your score drops the longer you take, so dawdling costs you.
Can I use a calculator?
You could. We'd know. Your conscience would know.
