Knowledge without Proof

If we know that x – x = x / x – 1
where x - x = 0
and where x / x - 1 = 0

But we cannot prove x – x = x / x – 1
given that we cannot prove x - x = 0
or that x / x - 1 = 0

Then how can we know that x – x = x / x – 1 without proof.

x - x = 0

add x to both sides of the equation. You get:

x = x

Any number is equal to itself.

0 = x/x - 1

Add 1 to both sides of the equation. You get:

1 = x/x

Multiply both sides by x. You get:

x = x

What's the problem?

Code:

But this does NOT imply that the original statement, -1 = 1 is TRUE

Multiplying a negative number by a negative number yields a positive number. 16 has two square roots +4 and -4. There is no implication that +4 equals -4.

Matehmatics is not about implication.

I don't know how they teach "maths" in England. But in "mathematics" in the US this is a silly question.

ps - You are trying to mix pseudological word games with MATH. NO "S"

But I'm not in England.

I won a National Merit Scholarship and scored in the top 2% on the SAT. Higher on math than on verbal.

In my opinion schools are designed to sabotage children's minds. In order to be regarded as intelligent by White morons you have to think what the White morons tell you. Even if it is stupid. I started ignoring teachers in grammar school.

I have noticed technology doesn't care what people think, regardless of color.

Who's trying to fool a mathematician.

I wouldn't expect a mathematician to ask a question that dumb.

I was repairing direct-coupled complementary symmetry amplifiers with differential inputs 30 years ago. I'm so stupid.

I post links to make it easy for people to research what I'm saying so they can judge for themselves whether it makes sense.

I never thought very highly of idiotic busywork tho. When the math teacher gave assignments I would do the three hardest problems and throw it in the garbage. I would get an A on the test anyway so the worst the teacher could do was give me a B. Who cared. LOL

I acquire knowledge to do things with, not to show other people I'm smart. The purpose of the internet is to distribute knowledge so other people can acquire power. Not solve useless mathematical trivia.

Which of my links are you complainig about? You haven't before now.

Shit!! if my aunt had bollocks she would be my uncle!! thats the only equation I can work out!!
You boys are clever dudes!!

On thinking things over I agree with 'Blackmatta'. And on thinking things over a little further, I think we can get even more basic than the axioms of algebra.

For example, how about this proof of x - x = 0?

Take group one of x objects - 1, 2, 3, ......... x

and group two of x objects - 1, 2, 3, ......... x

Now take one object from group one and one from group two, pair them up and throw them away. Do the same thing with the second object from each group, and so on. When we have thrown away all of the objects from group one we have also thrown away all of the objects in group two and so the remainder is zero.

So it would seem that we can prove that x - x = 0.

Division is the process of finding out how many times you can repeatedly subtract the denominator from the numerator.

For example suppose I have this many objects in the numerator ||||||| and this many objects in the denominator |||||.

I line them up like this

|||||||
|||||

Pairing the first of the upper and lower I throw them away leaving

||||||
||||

When I continue the process I find that I can take ||||| from ||||||| one time and have a remainder of ||.

So dividing x/x-1 if I pair them up I find that I can subtract x-1 from x one time with a remainder of 1. That is it equals 1 + 1/x - 1. And according to the counting proof above x - x = 0 so x - x <> x/x - 1.

Hey, "Umbrarchist" i think i understand exactly what you were trying to say..... We can talk to each other, it makes alot more sense than to talk at each other!
