So, when I heard Gavin complaining about his son's math teacher I thought "Oh is Gavin encountering Common Core??" I realized he has an older child so he must have already been acquainted with this madness.
Common core math is absolute insanity, but it still uses PEMMDAS, so Gavin's son's math teacher is very wrong.
awesome! thanks, I admit, I didn't go back and check it before I posted. hopefully gavin sees that and doesn't go all his dad and call the teacher "paahh thetic" :D
