Like goldenbach conjecture or stuff . Ideas put in the comments. It isn't a maths club we try to solve things that have NEVER been solved before.

Possibly even more interesting is discovering new math patterns and such!

Wouldn't that be 0 (unless you're faffing around with countable and uncountable infinities)?

edit: half of my post was lost.
edit 2: wow this really hates unicode x. x - x == 0, should be true for all values of x even ∞

^ Mathologer has a nice vidya on this: http://m.youtube.com/watch?v=-EtHF5ND3_s

TL;DW infinity-infinity = literally anything

Edit: When googling for that I found this http://www.philforhumanity.com/Infinity_Minus_Infinity.html which is simpler.

Any way still interested?

Subtraction isn't formally defined for infinite quantities. So, no.

Also is x/x=1 when x=0 so we shouldn't always make x/x 0 same with x0 / x 0 supposed to be x the power of 0

there's no such thing as subtraction for infinity. Infinity is not a number that you can drop anywhere you want.

Infinity is not a number

Exactly it's a concept

Infinity, is, in fact, a process - it's the process of growing without bound.

Infinity is the process of approaching 1/x from the right at zero.

It's also the process of approaching x as x becomes arbitrarily large.

This is why infinity - infinity does not make sense - it is not the subtraction of two numbers, it is the subtraction of two processes of growing. If they are growing at the same rate, it will equal zero - but if they are growing at different rates, it will equal something else.

It is possible that one infinity is growing so much faster that infinity - infinity comes out to just be another infinity - another process of growth.

∞ * 2 ≡ ∞
∞ + 2 ≡ ∞
∞ - 2 ≡ ∞
∞ / 2 ≡ ∞

All of these rules cannot apply to any real or not real number therefore ∞ is not a number

Which therefore means you cannot do those operations on it xD

Yeah but what is 1/0 google says it's infinity ;( I thought it was undefined

1/0 is undefined, in general, because infinity is a process and not a number. 1/x gets closer and closer to infinity as x gets closer to zero, but at zero 1/x is undefined because infinity is not a real number. There's also another reason it is undefined in this particular case - although 1/x approaches infinity from the right (i.e. as a positive number gets closer and closer to zero) it approaches negative infinity from the left (i.e. as a negative number gets closer and closer to zero) and thus doesn't have a consistent sign.

No.. my point is that now the proof is invalid because you just did some operations that you couldn't

258 x 2 = 516

I'm fairly sure it's valid because it's proving a point by starting with assuming the opposite… I could be wrong though
