It was sixth grade for me, and I was in the special, early-morning math class exclusively for nerds.
No intention to start a political debate here, but as an engineer who has taken A LOT of math courses, from a technical standpoint, I love common core math. I think it teaches math as an exercise in reasoning and abstract thinking rather than just memorizing numbers. That would make algebra come a lot quicker and a lot easier. I'm making a big assumption that "Boogerface" is in public school and is seeing math this way. Either way, I feel it's good to teach both methods, as some students may excel with the memorization technique while others, such as I, need to figure it out each time.
