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.

I have stared at this for some time now. This example is the first one I understood:

It is very similar to how I wold calculate it, but why use the difficult way?!?
I can't calculate 26+17 in one go either, but instead of doing something weird, I'd simply split 17 up in 10s and 1s: 26 + (10 + 7) = (26 + 10) + 7 = 36 + 7 = 43.
Ok, I admit, writing this down makes it look weird, too. But not as weird as splitting 17 into 13 + 4.
