Get over yourself.

what do you think i am, a contortionist?

 

 

 

and im just saying ive seen topics very very similar to this locked in the past

 

 

 

There's a similar thread to it, not exactly the same

Nowhere, everyone got their money, you did the math in a confusing way, your supposed to add the $2 tip to the 25, which is 27 plus the $3 the guys got back, 27+3=30, the 9x3 part was just to confuse you, took me a while, nice.

Ive got a question for you somthing

 

 

 

Whats the meaning of life?

You got it =D>

 

 

 

I also have a mathematical proof that 2=1, wonder if it's worth posting. . .

Everyone is meant to find their own. There is no set "meaning of life" that everyone can use; everyone's is different.

 

 

 

Ya, just read Man's Search for Meaning, 200 pages about answering that exact question :-w .

True, there is proof 2 = 1, you can post if you want, its good to have people learn some more things.

You are driving a bus. Four people get on, three people get off, then

 

eight people get on and ten people get off,

 

then 6 people get on and 2 more people get off. What color were the bus

 

driver's eyes?

 

 

whatever your eye color is, that only works when you say it or only show one line at a time.

 

 

 

There was an airplane crash, every single person died, but two people

 

survived. How is this possible?

 

 

 

they were a couple, and therefore not single

 

 

 

 

 

 

 

 

Which is heavier: a pound of gold or a pound of feathers?

 

 

they are both one pound

 

 

 

What came first, the chicken or the egg?

 

 

a circle has no beginning

I agree, that should be interesting.

 

 

 

I can prove that 1+1=3, but that is philosophical rather than arithmetical.

Subject: "science"

 

Grade:9th

 

 

 

Einstein's special realativity theory states that "The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light."

 

 

 

this would mean nothing can travel faster than the speed of light. However, if something could travel faster than 186,000 miles per second, why could it not travel faster than a light beam?

this just means that the speed of light will always stay the same, not that nothing can go faster than it.

Here is proof that 2=1

 

 

 

Let a=b, a and b are real numbers

 

 

 

a*a=b*a

 

 

 

a(exponent 2, or squared, can't do it on my keyboard)=ba

 

 

 

a(squared)-b(squared)=ba-b(squared)

 

 

 

(a-B)(a+B)=b(a-B)

 

 

 

a+b=b

 

 

 

b+b=b

 

 

 

2b=b

 

 

 

2=1

 

 

 

Disprove that :wink:

2b != b, unless b == 0, then 0=0

[somthing]

Very good explanation, couldn't have explained it better myself.

Who, me or r2d2?

 

 

 

r2d2, that's not an explanation if I understood it correctly.

You divided by (a-B), which is equivalent to 0.

 

 

 

Big no-no.

[r2d2]

I wasn't explaining it, I was disproving it. unles b=0, 2b cannot equal b, so 2!=1, but rather 0=0, or the expression is false.

Big no-no.

 

b(a-B) == b*a-b

 

 

 

you can multiply by zero.

[somthing]

R2d2, want to join? As to you N0M

[Rebdragon]

You divided by (a-B), which is equivalent to 0.

 

 

 

Big no-no.

 

b(a-B) == b*a-b

 

No, b(a-B) = b*a-b*b :-s .

 

 

 

you can multiply by zero.

 

Yes :-s (rendering the product 0), but you can't divide by 0. You can't do 1/0, 20/0, 0/0, infinity/0, x/0, a/0, anything. Mathematical laws require that you not divide by 0.

 

 

 

Thus, this is the illegal step:

 

(a-B)(a+B)=b(a-B)

 

\/

 

a+b=b

[r2d2]

I suppose I could, but what would be the point of that? add me if you wish, though I will post equally either way.

[Nom]

Reb got it right. Tricky little equation it is.

 

 

 

And no, sorry, I don't have time to do other people's homework on top of my own

[r2d2]

You divided by (a-B), which is equivalent to 0.

 

 

 

Big no-no.

 

b(a-B) == b*a-b

 

No, b(a-B) = b*a-b*b :-s .

 

 

 

you can multiply by zero.

 

Yes :-s (rendering the product 0), but you can't divide by 0. You can't do 1/0, 20/0, 0/0, infinity/0, x/0, a/0, anything. Mathematical laws require that you not divide by 0.

 

 

 

Thus, this is the illegal step:

 

(a-B)(a+B)=b(a-B)

 

\/

 

a+b=b

 

when did he divide? it's all multiplication.

 

you could say that if x is any number, the above means that x*0 = 0*x.
