Ok, so tell me what you guys think of this.

take any number

I randomly smashed on my keyboard and obtained 48395873947

add up all the digits (4+8+3+9+5+8+7+3+9+4+7 = 67)

repeat until you have a 1 digit number (6+7 = 13) (1 + 3 = 4)

now, subtract that number(4) from the original number (48395873947)

48395873943

your number is now divisible by 9

48395873943 / 9 = 5377319327

bonus fact: any number with digits that add up to 9, is divisible by 9 (example, 18, 27, 36, 45, 48395873943)

our number system is very weird. we count from 0 to 1, then 2, 3, 4, 5, 6, 7, 8, 9, then we kind of just, go back to the beginning, except this time we add a 0 behind the 1 (or in-front of, however you want to look at it) to make a 10

what 10 really means is 9+1. both of these numbers are contained within 10, except the 9 is concealed as a 0. we kind of just shove it under the carpet

11=9+1+1

12=9+3, or 9+1+2

now, after we get past 19, our formula no longer works

9+2 ≠ 20

but....20 is really just 2 10's (which is 9+1)

ah, now do you see?

20 = 9+9+2, or 9(2) + 2, or (9+1)(2)

21= 9(2) + 3

22= 9(2) + 4

99 = 9(9) +18, or 9(11) , or (9)(9+2) if you really want to break it down

now, 3 digits is where it gets interesting

100

the easiest way to write out 100 in terms of single digit numbers would be (9)(11) + 1

but 11 is not a single digit, so we have to go with the next easiest way

(9)(9+2) + 1

Now, I've figured out how to solve any number and break it down into the shortest problem using only single digit numbers. I thought it was pretty mind blowing to be honest with you guys lol

well those formulas and terminology are supposed to help you if you decide to get a math based major in college. Of course you have to pay for college, it's all a scam really. You should never have to pay anything to receive knowledge. It should all be openly taught, and of course we let the "students" choose what they want to learn. Math is fun and can help people get to the moon, for 1 tiny example. Why are we denying people who can't afford college the chance to benefit humanity as a whole?

:o:o:o:o:o:o:o:o:o

Yeah, I took a college math course. pre-calc, after algebra and shit. I got a B or a C, I can't remember, think it was a B cause they go by 10 point grading scale so it's like "hey, in highschool you were smart and now you got a 80 and you still have a B! GOODJOB DURR YAY" highschool was all about getting as close to 96, then you get an A and you don't have to strive for the extra 4 percent to impress anyone, you know? basically a way to keep us dumb and have us think we're smart.

I can agree with you on some level that it's boreing, seeing as they hardly show any effort to interest you. They just fucking cram formulas and laws and fucking omg I fucking hate memorizing sin cos tan and like the 1 billion other shit you gotta memorize in calculus fuck that shithtateatehahhgha I thought it was going to be easy the first weeks...my grade started to slip when that shit got hard as fuck to get good grades on tests when you can't remember 1 little formula, and plus my teacher was a COMPLETE BITCH

she would take off mad points for not showing ALL YOUR WORK like, every fucking step and it's like wow bitch if you don't see how I skipped a few steps in my work to save paper and because it was kindergarden math to me at that point and easily solved in your head, then you're not a fucking math teacher

they never really show you how planets move and shit

at age 13 all children should have the knowledge from public schools to tell you where constellations are and what phase the moon will be in and shit, like forreal wtf did you really learn in school. you learned how to talk to people, bullshit, cheat, and whatever other fucking crazy adventures you had in the hallways lol

Now that is pure truth :thumbsup:

The best things you learn at school are learned outside the classroom.

are you saying you've learned more from college? your sentence is implying that you've received additional education somewhere other than public schooling

seriously does anyone else see this sentence as a mind fuck

11111111111=9(1234567901)+2

1111111111=9(123456790)+1 OR 9(123456789)+10

111111111=9(12345679)

11111111=9(1234567)+8

1111111=9(123456)+7

111111=9(12345)+6

11111=9(1234)+5

1111=9(123)+4

111=9(12)+3

11=9(1)+2

1=9(0)+1

111,111,111(111,111,111) = 12,345,678,987,654,321

(9(12345678)+9)^2 equals same thing heheehee

I didn't know about that before though, aren't 9s amazing!?

Also, 4's are pretty dope too, check this out kids...

3's do the same thing, except they repeat 3,6,9 to infinity, 9 of course repeats 9
