Hello, and thanks for pasting in your answer!
It's due to your having non-ascii characters. The parentheses need to be ascii characters.
You can copy and paste this in
(200 - 2 ) * 0.65 - 100
as this'll work. It's not a common issue, so an improvement and lower priority, but I'll add this on to an existing issue; it may be possible to provide a better error for non-ascii characters being used.
Let us know if you have any other questions!
