1 + 1 = 2
Math isn’t competitive, it just is what it is. You either get it correct or you don’t.
It’s like jumping across a 10 foot wide ravine. You either jump across or you don’t (and fall in the the ravine). There is no almost jumped across.
Insisting that 1 + 1 can only equal 2 is somehow racist, sexist, bigoted, homophobic, etc. when it comes to math education.
However, try using Million Man Math or, better yet, Common Core Math to your advantage when preparing your taxes and watch what happens.
