As a Maths teacher I have known this for a long time. It arbitrarily adds brackets to 8/2, elevating it's precedence from "division" to "brackets", thus returning a wrong answer. As a programmer it embarrasses me to hear some of them say "you don't need to know Maths to be a programmer!" - well, look where that's got us.

Re the later comments that the Kenya issue has been fixed (still wrong for me), Google have been told multiple times they're doing the Maths wrong - still broken.
