Free mental maths drill — instant play, no signup, no download
Speed Math Blitz is rapid-fire mixed arithmetic against a clock. Mixing the operations is deliberate: switching between addition and multiplication carries a small cost every time, so a mixed drill is harder than the same number of single-operation problems.
Press Start to begin the timed run.
Solve each problem and submit.
Operations are mixed — addition, subtraction, multiplication, division.
Correct answers immediately load the next problem.
Your score is problems solved before time runs out.
Choose the operation (addition, subtraction, multiplication, division or a mix) and a difficulty that sets the number range, from 1–9 on easy to 10–999 on insane. Multiplication keeps one factor at 12 or below (and the other at 12, or 30 on insane), and every division comes out exactly.
A correct answer scores 10 points, 15 once you have three in a row and 20 from five in a row. A wrong answer scores nothing, resets the combo and shows you the right answer for a second. Your best score is saved in this browser.
Arithmetic fluency across operations, including the switching cost between them. That switching cost is real and it is why mixed drills feel harder than their difficulty suggests. More math games to try next: Chain Math and Square Root Sprint.
Arithmetic fluency matters more than it seems. A 2013 brain-imaging study found that how strongly children engaged a region involved in fact retrieval while doing simple sums predicted their maths exam scores, independent of general ability — fast recall frees working memory for the harder parts of a problem.
Time pressure has a cost for some people, though. Research on maths anxiety shows that worry consumes the same working memory that calculation needs. The practical answer is short, low-stakes timed rounds you choose to play, which build speed without the exam feeling.
Read the operator first, before the numbers. Committing to the wrong operation is the costliest error here.
Learn the shortcuts: ×9 is ×10 minus the number; ×5 is half then ×10; ÷5 is ×2 then ÷10.
Do not verify. A second look costs more than the occasional error.
Division is the slowest for most people. Practise it deliberately rather than hoping for addition.
Switching between operations carries a small reconfiguration cost on every switch. It is small individually and adds up across a run.
Very similar; this run is shorter and paced faster. Use whichever you prefer and compare against itself.
It is the single biggest factor in a good score. Everything else is technique on top of recall.
Most people gain substantially in the first two weeks of daily practice, then improvement slows markedly.
