Why math is so complicated.

i saw it in wikipidea and wanted to show it to my teacher so i saved it on the subdomain lol.

I like the part where it divided by zero.

WTH ?

Since A = B, (A - B) = 0 and x/0 is undefined. The proof fails at step 5. The proof actually ends at step 4 with 0 = 0. Neat though, none-the-less.

I've been studying math for a few years now and a little more with my current uni degree... Complex??? not really... At the end of the day most forms of maths can be broken down into simple arithmatic methods...
It dose however get complex when you start taking about proofs and complex numbers... Then it can become a really headache. The idea that just because you can't calculate it dosn't mean it dosn't exist. In fact complex numbers have been proven to exist... but you need a multi dimensional plane with which to accurately plot it. But in the end you don't need complex numbers and complex maths unless you plan on studying Quontum Physics or something like that. To do that though you need to be some kind of maths genius anyway.

The best example of defining maths was offer by my current maths lecturer and it goes something like this

Natural numbers (1 to inf)
are in
Integers (-inf to inf)
are in
Real Numbers (expressible fractions)
are in
Rational Numbers (A number that exists within the linear plane of numbers, ie Pi, root 2 | can't be express by fraction but can be said to exist rationally)
are in
Complex Numbers (Complex numbers are sometimes called imaginary numbers, they exist in multiple dimentions of space and not simply on the linear plane of numbers | this is where quantum physics comes into it)

Now all maths from here is the simple application of logic, similar to how you would program logic into a CPU (except complex number which behave quite differently)

The equation in the link is actually very simple logic, maths is about proof. the write has prove that it is possible for 2 = 1
think abstract you are talking quantity of properties for example if b = 0 then 2 * 0 = 1 * 0 ( this would be a much simpler proof than the proof that the writer has provided. but you arrive at the same conclusion.
2b = b
let b = 0
2 * 0 = 1 * 0
drop the zero
2 = 1 (in reference to property b (which can be any neutral property, in maths neutrality is represented logically by zero)
hope that helps
remember Maths is about proof not calculation. That is the concept many people fail to grasp about maths
