One student got tired of being dumbed-down by Common Core's convoluted "standards" to do basic arithmetic.
"Standards" like how to add two numbers, which the student was told to do like THIS:
WHAT? It's enough to make you pull your hair out.
So when he was given his next basic arithmetic assignment, to find the difference between 180 and 158 (180-158), this 5th grade student just did it his own way -- the right way -- and dissed Common Core with single, awesome word:

That’s pretty good.
Brilliant, that’s the loudest I’ve laughed in recent memory.
how stupid
Explain how you got your answer.
“Math”
This “could” be explained in algebraic notation, and it might not be all that bad a way to juggle numbers in one’s head. On paper, “common carrying” beats the pants off of “common core.”
Here's a visual on the stupidity. Put a pile of 27 pennies and a pile of 16 pennies on a table. Now go through those manipulations. Absolutely no logic.

Let’s see: 26 + 17 + ??
6 and 6 are 12. Plus one is 13.
2 and 1 are 3. Plus the carried one from the 13 make 4.
The answer is 43. Took about 5 seconds to do in my head, even without being able to add 6 and 7 directly.
I’m not sure how, exactly, that “common core” method is supposed to come up with an answer.
Reminds me of the shortcuts I use to do math quicker. The catch is that I can make shortcuts because I understand the underlying basic math. If this is advanced material taught after the basics have been learned then I don’t have a problem with it. If it’s being taught instead of the basics then that’s a problem.
26 and 10 is 36, and 7 is 43.
Wooo-hooo! My husband, who is an aeronautical engineer (and a retired Naval aviator), LOVED this intelligent young man’s answer.
;-)
You are right.
I think they are trying to keep things at 10 and under, so kids can count on their fingers.
(Which I do, as part of my shortcuts, sometimes.)
I think you’re supposed to do it like this:
26 + 17 = (30 - 4) + (20 -3)
26 + 17 = (30 + 20) + (-4 -3)
26 + 17 = 50 -7
26 + 17 = 43
Is this simpler, clearer, offer more insight or require fewer manipulations than:
26 + 17 = (20 + 6) + (10 +7)
26 + 17 = (20 + 10) + (6 +7)
26 + 17 = 30 +17
26 + 17 = 43 ?
I’ll keep and open mind. I am sure it will actually end up confusing more gammer skool math teachers than it will enlighten any students.
Fingers. Inspection. Etc.
I would trust an aeronautical engineer to teach common core, but not a public school teacher.
“That’s real retarded, Sir...”
One can devise number systems to count to well over 10 just using ones fingers.
“26 and 10 is 36, and 7 is 43.”
I do it this way mentally...
25 + 15 = 40.
1 + 2 = 3.
40 + 3 = 43.
