How do you make 24?




A few Honors classes today got a few problems like this:

Use any arithmetic operation +-x÷or () to make these numbers equal 24.

3, 5, 6, 7 (answer [6-5+7]x3=24)

This is a common game that is great for building logic skills and number sense. If you’d like to play more on your own, try this link. It’s good for your brain.
