You realize schools are just indoctrination centers not focused on creating intelligent people, right?

Fun fact, common core math was invented by a communist
And look how shit it is

287 what is this fucked up shit. Math, its a constant in the universe? Why does it need to be made more fucked up? This is like heres directions to my house we are standing in front of. I want you to go around the block, get on a plane, fly to China then come back here.

What is this shit?

>Europoors will never have this quality education

This is why they are the worst

>>139934236
I get what they're trying to say but it's just so retardedly said because even the retarded kids are expected to understand it.

You have 325 and 38.
You can get to the nice, easy number 300 by taking 25 from 325. So take 25 from 38 too.
That leaves you at 300 and 13.
Now take the 10 from 300, leaving you at 290. Same with 13, now at 3.
290 - 3 = 287

There. It's the same "method" they're trying to do, but not covered in steaming horseshit swarming with flies.

This is how I've counted since I was young, noone taught me.

It the most efficient way to deal with large numbers.

If we actually had schools teach Christianity then we wouldn't have all these faggot atheists everywhere

>>139934236
They're training them how to be cashiers, who have to subtract whole numbers all day.

Anyone with a brain will figure out the quick way on their own. Smart kids will be smart.

Math is too hard goy, you should just dig ditches and let us educated people handle the difficult work.

>Subtract 38 from 325
Okay, I remember being a kid who struggled with and fucking hated math throughout school. I'd always lose track of shit and have to start over. So I distinctly remember breaking shit up into pieces and using tricks to make it easier.
But what is this overly-complicated horseshit?

>325 - 38

>ignore the hundreds place for now, just look at the tens and ones places
>38 > 25, so you can take all of the 25 away from 325, giving you a nice, round 300
>but you're not done, how much more do you have to subtract? 38 minus the 25 you've already taken away, that's 13
>13's not a round number, wahhh, split it up even more if you have to
>300 - 10 = 290, and 290 - 3 = 287

>but no
>let's counter-intuitively use addition and circle a bunch of shit
>just dishearten the hell out of these kids who thought that we were supposed to be making this shit easier for them
Fucking knock it off, common core. Or whatever the fuck this even is anymore. Every revision just makes things worse.

Replying from the front page, didn't even see this already.
That just makes it all even more retarded.

>>139935755

that would be my thought process also

This is not the voodoo magic boomers make it out to be. This just attempting to teach methods of performing mental math to kids who were too dumb or uncreative to come up with them on their own. To normal people this is common sense but for the borderline retarded their expected train of thought has to be clearly outlined.
