One to Nine Equals One Hundred Quiz Puzzle Answer

A while ago we posted a puzzle about making one hundred from the digits one through to nine, and you can try that here if you are interested. This week we have a similar puzzle about making one hundred from the numbers one through to nine.

As before you have to use the nine numbers in order; that is, you have to construct a sum starting with the number one and finishing with the number nine, and using just the four common arithmetic operators (plus, minus, multiply and divide), and no brackets. NB you do not have to use all four, but you can't use any others.

For example, you could have

1 x 2 + 3 + 4 x 5 - 6 + 7 + 8 + 9

but that equal 43, not 100.

So, can you make a sum of this form that equals 100?

The answer is

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 x 9

Did you work it out?
