Requesting a topic

If a topic or problem type you need is missing, tell me:

  • the topic and the grade or course it is for,
  • one or two example problems of the kind you would like, and
  • whether the answers should be whole numbers, fractions or decimals.

Requests help decide what to build next. I can't promise every topic, but I do reply to every request.

Reporting a mistake

Accuracy matters most on a math site. If an answer or explanation looks wrong, please include:

  • the page address (for example, mathgem.ca/algebra/solving-equations/),
  • the settings you used (difficulty, operation, digits),
  • the Set ID printed on the worksheet, and the problem number, and
  • what you expected the answer to be.
