Hi,
i would like to suggest you to check a math colculation with Excel:
-5^2+25
by math rules should be equal to 0, but Excel is calculating result as 50.
I doubt there is a (maybe known) problem regarding the order operator precedence in the expression parser.
This was a tricky game in the social... but finding that Excel is calculating wrong... i'm here just asking you.
Regards,
