i saw an equation in my dreams lastnight! opinions?

[Kilgore Trout]

So, again, what is halfway between -1 and 1?

 

[ladybug77]

Don't confuse philosopy with math.

Im explaining it THREW math. Our math is wrong

Says the person who thinks -1 = -1/2.

Please, remember to take your meds.

And stop throwing math.

 

[sandy whitelinger]

It has errors. 0 is really just -1. There is no nuetral. O isnt anything except a place holder...

And if you repeat it often enough... Just ask Goebbels.

-1/2, is the same point on the line as 1/2

 

[Poeticus]

Zero isnt a natural number

It depends on the textbook in front of you. Algebra textbooks will say it's not, while computer science and logic textbooks will say it is.

Either way:

It's still a part of the number line. The center most part.

Im explaining it THREW math. Our math is wrong

So is this answer.

 

[Willamena]

Its because this is the wrong term. We are including motion. A movement isnt gaining or losing number.

But maths is! Maths is gaining and losing in the playing field.

More is more. Less is less.

Its displacement of the object on a line in time and space.

Its the number of steps he is taking that matters...not the starting point. So in this senerio, it doesnt HURT to use the zero...but it makes no difference to throw it out either.

On exchange of objects...the zero cannot be there.

The zero is there, too, in exchange of objects. It is there in the nothing you hold after someone else has taken the pencil, and the nothing you hold before someone has given you a pencil.

Movement and time give context for zero.

Zero isnt a natural number

This says it is Parity of zero - Wikipedia, the free encyclopedia

Parity of zero - Wikipedia, the free encyclopedia Note 1.

^ Penner 1999, p. 34: Lemma B.2.2, The integer 0 is even and is not odd. Penner uses the mathematical symbol ∃, the existential quantifier, to state the proof: "To see that 0 is even, we must prove that ∃k (0 = 2k), and this follows from the equality 0 = 2 ⋅ 0."

-1/2, is the same point on the line as 1/2

So -1/2 = 1/2? You also implied that -1/2 = -1.

You sure have a lot of ways of naming the same number.

Thats out of context. I didnt say that. It depends on how you apply it.

If i had 500 pencils, and i gave them all away. I have -500 pencils. But -500 hundred, is just -1 repeated 500 times.

If you gave them all away, you would have:

500 - 500 = - 1

Therefore, you would have the absence of one pencil.

 

[sandy whitelinger]

If i had 500 pencils, and i gave them all away. I have -500 pencils. But -500 hundred, is just -1 repeated 500 times.

So by that logic you have x (the amount of pencils in existence)-y (the amount of pencils you have)= minus a poopload of pencils.

We aren't. This is key. What we are describing is after and before motion.

Its displacement of the object on a line in time and space.

The amount of displacement has a value. 5 feet forward is a displacement of 5 units. Generally, displacement also has direction (normally, it is represented by vectors, but as we are having trouble with 0 let's not introduce those).

it doesnt HURT to use the zero...but it makes no difference to throw it out either

How much (in pounds) does a photon weigh?

On exchange of objects...the zero cannot be there.

Let's say you have several molecules of water that you split into hydrogen and oxygen. How many molecules of water are left?

 

[Kilgore Trout]

Thats out of context. I didnt say that. It depends on how you apply it.

Ah, so different numbers equal different amounts depending on how much insane gymnastics you have to do to get your ridiculous system to work.

So, where do -1/4 and 1/4 lay on your number line? What about -3/4 and 3/4? Does 1/4 = -3/4?

Are you ready to stop this silliness now?

 

[ladybug77]

So -1/2 = 1/2? You also implied that -1/2 = -1.

You sure have a lot of ways of naming the same number.

The original question was this: what is -1/2 +1?

Its 1. Unless i have to give a half back, then its 1/2.
Its not wrong.

 

[Kilgore Trout]

The original question was this: what is -1/2 +1?

Its 1.

You also said that -1 + 1 = 1.

Therefore, -1/2 = -1.

If you cannot understand this simple concept, you need to go back to second grade.

Generally, displacement also has direction (normally, it is represented by vectors, but as we are having trouble with 0 let's not introduce those).

You have just made me giggle.

 

[sandy whitelinger]

We dont have to elimate the zero as a symbol. We elimate it being a number.

The number 10 for example.
Its the number 1, 10 times.
How else where we suppose to write it?
So we used a symbol to represent a two digit number.
The zero at the end is an equation to calculate the value of 10.

The zero does NOT belong on the negative and positive scale.
Its a placeholder. It cant be there, when all other numbers are present. It doesnt belong there.

Did you by any chance work on the Mars Climate Orbiter project for NASA?

 

[Koldo]

The original question was this: what is -1/2 +1?

Its not wrong.

If - 1/2 + 1 = 1, and - 1 + 1 = 1, then - 1/2 = - 1.

If x + 1 = 1, and y + 1 = 1, then x = y.
