Math CentralQuandaries & Queries


Question from Britney, a student:

I have a math problem with the game 24. I am not sure how to solve it. You can use +, -, multiplication, division, ( ), square root, and exponents. Please help me. The numbers are 1, 6, 7 and 8. You have to use all the numbers and you can only use them once.

Hi Britney,

My solution uses a square root. Can anyone do it without a square root?



Did Penny's hint help? Think about it for a while. If you still don't see it here is another hint.

Hint: 1 + 7 + 8 = 16
