Now, you probably now that this is because 0 and 1 are the identity elements of the additive and multiplicative groups of real numbers, respectively. Probably wouldn't've helped you as kid though
- jon_richards 2y agoI think it's much more productive to teach children 2x0 = 2x1 + 2x(-1) = 2-2 = 0 and 2xx0 = 2xx1 x 2xx(-1) = 2/2 = 1 Inverting the concept and having those patterns stem from a fundamental identity can wait until its not seen as the mathematical equivalent of "Because I said so".
- Etherlord87 2y ago"Children" at what age do you want to teach this, and how many children are you in contact with? Because that one kid probably suffers from autism.
