1 through 9

Using the digits 1, 2, 3, 4, 5, 6, 7, 8, 9, can you make 100?

You can use addition, subtraction, multiplication, and division, as well as brackets.

However, they must stay in the same order and you cannot join two digits to make another number, e.g. 1 and 2 cannot be used together as 12. The RiddleDude can find three different ways to make this work. Can you?

  • 1 * (2 + 3) * 4 * 5 – 6 + 7 + 8 – 9 = 100

    Make that four solutions!

    Great job, Jimmy Barcus. There are still three more solutions out there everybody.

    123 + 45 = 168
    168 – 67 = 101
    101 + 8 = 109
    109 – 9 = 100

    Here is the result

    123 + 45 – 67 + 8 – 9 = 100

    Nevermind, I thiught we could join the numbers into another number. Haha! Sorry for my mistake!
