The basis of common core is for ppl who cant ****ing add "complicated" numbers so you basically turn one number into something simple like 10 then add the difference.
8 + 5 = 13
8+2+3 = 13
so 10+3=13
they just take 2 from 5make it 3 so 8 can turn into 10 which is easier to add to.
ITs ironic how common core is for ppl who cant think so the workaround is doing multiple math equations lol..
But that can be said about everything on this planet.

I had no idea wtf they were doing up there, this explained it. It is actually pretty much what I have done in my head all my life anyway without realising. I'm usually the best in any room at mental arithmetic u know - I'm a top flight mathlete

This is so they know you have the basic procedure correct b/c it leads into more advanced areas of maths. You may not have progressed that far so it probably doesn't matter TBH, I mean how many numbers are there on a telemarketers phone keypad anyway, amirite?
