You count up from 12 to 32, using easy incremental steps
12 + 3 = 15, then 15 + 5 = 20, etc util you get to 32.
So it could be done shorter as well:
12 + 8 = 20
20 + 10 = 30
30 + 2 = 32
------------
8 + 10 + 2 = 20

And what exactly is this "Incremental steps"? Who says you cannot count up from 12 to 32 like this?
12 + 20 = 32
» 32 - 20 = 12
or
» 32 - 12 = 20
and as such
20 - 12 = 8
(How do I know that? Well take 32. 3 X 2 = 6 + 2 = 8) 
I mean even easier still is take the original problem 32 - 12 = ?
3-1=2_ 2-2=_0
» 32 - 12 = 20

How is that easier than the simpler way of just saying 32 - 20 = 12. Idiots.

Is this a real thing? It looks a lot like one of those math troll threads that occasionally appear on .. a certain site.

O Lordy yes, it is a real thing. My wife teaches the gifted in elementary and I have seen this stuff. I think it comes from Singapore or somewhere like that (I saw a book about the method and it had some far away country in the title). Little by little people are starting to question the value of it.
Mercifully, my youngest is in the 8th grade and has only had a small sampling of the mathematical madness.
I think it all comes from people trying to publish for their Ph.D.s. Create a "new and improved" math concept as your thesis.

One of the guys at work was talking about this the other day. They are teaching his 6 year old to do math this way. Seems messed up. But with large numbers that is exactly how I do it in my head. There are probably better ways to do it though.
All in all, seems really messed up to me.

Maybe it's because a minus sign promotes negative thoughts about math...

And just wait until they move on into programmer roles in the future. Just imagine the length and breadth of their algorithms and functions to accomodate their Common Core stuff.

Common sense says: If it ain't broke, don't fix it.
That's what we got here: failure to apply common sense.
"Old" style mathematics got a couple of guys on the moon, lots of stuff in space and all these computers/devices we like so much. That means at least some of the old style calculations got it right.
Change for the sake of change is just plain stupid.

It is determined largely by partisan political motivations. To keep it lounge-safe, I'll just say that where you are is a different political side than the national political side that is giving/taking money from local political bodies for accepting or rejecting this political agenda.
There... I didn't argue about politics.

I think the idea is to move from the lower number to the larger number in small steps that are each easy to do:
3 + 5 = 8,
8 + 10 = 18,
18 + 2 = 20
Yay! There is the answer!
The old way way was obviously way too complicated where you have to do:
The "ones" column: 2 - 2 = 0
The "tens" column: 3 - 1 = 2
...and then you wrote the "tens" answer followed by the "ones" answer to get 20
Yay! There is the answer!
Of course, you could make it even easier by only incrementing the lower number by 1 until you reached the larger number and then counting how many times you had to do that. 20 Yes! That should be the new method! Much simpler!
Or, for future programmers using nice round, easily remembered numbers:
12 + 4 = 16
16 + 8 = 24
24 + 8 = 32

My son's going through this now and it's driving my wife crazy. I've reviewed it and I think I understand the "why" behind it. I've started thinking I look at numbers differently than her. Most Americans learn math by memorization - flash cards, repetitive tables, etc. They don't think about what the numbers actually mean. They are stuck as they have only memorized base 10.
What happens when you need to understand base 2, 8, 16, 535? The majority of Americans can't figure those out. They never had flash cards for that. However, this is teaching kids early how to understand the value of the number outside of what they have memorized.
