This quiz suits primary pupils firming up their tables, older students who want more speed and parents practising alongside them. The first questions cover the products people mix up most, then they move on to sums you can solve in your head with a shortcut rather than by working them out on paper.
Every answer shows a method: splitting a number, rounding to a ten, spotting a pattern. Tip: if an option looks plausible, check its last digit. The units digit of a product depends only on the units digits of the two numbers, so 13 × 4 ends in 2, just like 3 × 4.
