I don’t understand what all that gymnastics has to do with 12 + 12. I simply memorized 12 + 12 = 24 like 40 years ago. Along with a bazillion other math facts they had us memorize in school. Back in the days before computers & smartphones rotted our brains.
It’s easy to do in your head
2 + 2 is 4 and 1 + 1 is 2 and 4 + 2 is 6, easy
