I can't find a way to do this without using a variable to return the result; Which may be fine if you're only calculating something at runtime, but what if you needed to calculate based on user input in the textbox? ;
{Var1 = 10/(2*(2+3)) ; textbox.text = Var1}
You can't turn the textbox string to an integer because the result will end at the first operand.
if (textbox.text == "2+3"){int(textbox.text) = 2}
You could maybe do some voodoo magic with tokenat and teach it the basis for pemdas but that's silly. So, I'm interested in the answer as well it seems.
