Mathematical order of opperations in script is wrong

[TomNysWF]

Describe the bug
As seen in the screenshot below, the math is wrong when doing A - B + C. It seems to interpret it as A - ( B +C ) instead of the normal order of opperations. As a bonus issue (altough not really a problem) there seems to be a weird floating point issue

How to Reproduce*

As seen in the above screenshot, a simple script is enough to reproduce this error.
