Brain Game: Math Friday
By BY
This is either late for Math Monday, or early for Math Monday. I'll let you decide which. Good luck!
Using exactly FIVE plus signs and ONE minus sign, make the following calculation work: 1Â 2Â 3Â 4Â 5Â 6Â 7Â 8Â 9 = 100
Here are two SOLUTIONS.
SOLUTIONS:
I know of two. If you find another solution that meets the rules, please post it in the comments. Thanks!Â
1 + 23 - 4 + 56 + 7 + 8 + 9 = 100
12 + 3 - 4 + 5 + 67 + 8 + 9 = 100
