Quick Math

Math operations against the clock. How many can you solve?

1. Solve 10 mental math problems by picking the right result from four options.
2. Click or tap your answer; only your first pick counts. The right answer turns green, yours turns red if it was wrong, and the next problem comes up by itself.
3. You get 10 seconds per problem, and the timer turns red for the last 3. If time runs out, it counts as a miss.
4. Problems are additions and subtractions that get bigger as you go, and the last one may be a multiplication. At the end you'll see your score out of 10 and your accuracy.
5. Start with the last digit of the result: it is often enough to rule out options and save time.
