B-but you don't know what the teacher taught during the lesson!

This was all explained in the lesson! You just don't have the context!!

>We meet at the bottom
Murica'

That's precisely how I do math. It's very easy for large operations, and helps kids understand the concept of reciprocation.

>"write a letter to Jack"

nevermind the weird calculating method, but writing the answer in form of a letter? this has to be fake.

what the fuck is this shit?

Fucking burgers man

Idiots who can't do math in their head (pol) don't understand that common core is just "Doing Math in Your Head For Dummies." It teaches kids how to use the methods that those that are naturally talented are already doing mentally.

my thoughts exactly, what the fuck is this? Aren't these all some funny 9gag-tier 'jokes'?

I thought you'd use some combination of R, SPSS, Matlab, GNU Octave, Julia, MS Excel along with whatever overpriced specialised programs you have at your job.

Or a calculator if you're just doing back-of-the-envelope calculations.

>that healthcare statement for republicans

this is not the worst one of these I've seen

8+5-2 = 10

Shithole country education >>>>>> murican (((education)))

This is what happens when you allow jews to 'educate' your children.

thats common as hell for those 'spot the mistake' questions

15? 20? 30? Where did these come from? I genuinely think whoever came up with this needs to be dragged out onto the street and just chop their fucking head off with a machete right in the middle of the town square. This is garbage.

wtf am i looking at?

If kids can't figure these methods out alone in their heads they aren't going to be smart enough to grasp it on paper.

Only time I do multiple steps is if I'm in work and actually doing it in my head.

Example: 35*8

I'll just say 35*10 = 350 and then because I'm not a complete fuckwit, I'll naturally subtract 70 and reach my answer accurately in about 1 second total.

Or you could do 3*8 (24) and 5*8 (40). As the first bit is "tens" you add a zero. 240+40.

If a simple subtraction needs like half a dozen operations to complete, it's time to kys.

I like that. It seems like it encourages "out of box" thinking.
I see now why a lot of people feel threatened. Norms are being threatened.

How the fuck does it work?

There's no limit to 'out of the box' thinking though. You can come up with an infinite ways to get your answer at that point.

Fuck off. The letter posted above is correct.

Simple > Complex > Complicated.

This is mathematics, where accuracy and speed in calculation actually do matter. Especially if you are automating the computation. God forbid we need designated super computers to calculate the P&L statement for a company because some beta nu-male teacher over-complicated teaching.

This is idiotic. 32-12 is its own problem. 12+3; 15+5; 20+10; 30+2; 3+5+10+2 are all their own problems.
There is no real correlation between any of the latter problems and the former other than just saying the latter most coincidentally is similar in it's result to 32-12.

It seems like a preferential thing, and completely wrong to teach kids. Maybe as an example, but as a problem solving method? Fuck no this shit just gives me a headache.

Shit head. Do math normally. 8 x 5 is 40. 8 x 30 is 240. 280. Done why the fuck would you make up an extra equation, then add a subtraction step? Get fucked.

This isn't a talent. This is nonsense.

>proud white Argentinian believes 8+5=10

This is straight doublethink and you should be ashamed for promoting it.

Wait did you get the numbers wrong or am I missing something?

35*8 = 70*4 = 280
