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!
