Hmm.

  Total: 21
  You beat 70.22% of people.
  Time per question: 1.43s
  Your slowest question was 20 ÷ 2 = 10, which took you 2.24s.
  Try to be faster next time!

Looks fun! I made a small JavasScript snippet to solve it by pressing "Enter" at whatever speed you want ;)

  const observer = new MutationObserver(() => {
    document.querySelector("#answer").value = eval(document.querySelector("#question").innerText.replace("=","").replace ('x',"*").replace("÷","/"));
  });
  observer.observe(document.querySelector("#question"), { attributes: true,  childList: true, subtree: true });

¯\_(ツ)_/¯

Hang on, those aren't only sums. Got 22 correct, which I guess may be fine for a tired Tuesday evening.
