1, 2, 3, 4, 5, 6, 7, 8, 9 equals 100 ... right?

Jul 22, 2021 | Hinsdale

Happy July! Time for a math puzzle...

There are at least three different ways to use the numbers 1-9 in that order without multiplying or dividing in order to reach 100. Here's one possible way:

123 + 4 - 5 + 67 - 89 = 100.

Can you come up with any other ways? Here are the rules: use every digit in order - 123456789 - and insert as many addition and subtraction signs as you need so that the total is 100. Remember the order of operations!

Write down your answer and bring it in to Ms Alex or Ms Antoinette by August 20th for 3 bonus punches. Good luck!
