I would say yes, because based on this monstrous "common core" analysis of how to subtract one number from another -- rather than enter one number, then the second, then hit the minus key, we have a convoluted mess. See: http://thetruthwins.com/archives/you-won...ubtraction (it's probably been pasted here before) But somewhere, someone in America decided to make it harder..... oh, what a silly act that was. When I first looked at this method, I thought it was a way to avoid the carry, but in the following example, a carry is still required: 43 + 89 43 = 3 + 40 89 + 3 = 92 ; carry 92 + 40 = 132 So I don't see how this method simplifies anything. " I can't calculate 26+17 in one go either" - Why not? |
