You forget who you are writing to. The last math I had was not math, it was arithmetic!
22 years ago. And I did POORLY.
I was stumped on the driving question (both turn left, etc) until I drew it out on a piece of paper. Since I long ago forgot the formula for the open side of the triange, I guestimated.
I usually feel like an idiot when I see a lot of the educated banter here.
