Text captcha does not obey order of operations
The text captcha asks a simple math question, for example:
six plus two multiplied by four The correct answer is 6 + 2 × 4 = 6 + 8 = 15, due to order of operations, but the captcha system does not accept that and instead expects you to do (6 + 2) × 4 = 8 × 4 = 32. This is confusing to many users who do multiplication first, as they should. Please explicitly specify that order of operations is ignored, or do not ignore the order of operations. Or accept both answers to the ambiguous question (e.g. both 15 and 32).
I tried to post this on https://trac.edgewall.org/newticket, but they have blocked submissions by Tor users. I am posting it here instead in case there is a possible workaround on Tor's side.
