How do you prove something is equal?

To prove equality of an equation; you start on one side and manipulate it algebraically until it is equal to the other side. To prove a statement is true, you must not use what you are trying to prove. So I have shown that the two sides of the equality in red are equal to the same highlighted expression.

How many pages does it take to prove 1 1 2?

In my post about the myth that Logicians are crazy I mentioned in passing that Whitehead and Russell spend 300 pages proving 1+1=2 (but were both sane).

How many pages does it take to prove 1 1?

Some idea of the scope and comprehensiveness of the “Principia” can be gleaned from the fact that it takes over 360 pages to prove definitively that 1 + 1 = 2. Today, it is widely considered to be one of the most important and seminal works in logic since Aristotle’s “Organon”.

Did we actually prove that 2 = 1?

The truth is we didn’t actually prove that 2 = 1. Which, good news, means you can relax—we haven’t shattered all that you know and love about math. Somewhere buried in that “proof” is a mistake.

Is there any proof that 1+1=4?

While any proof that 1+1=4 would be a mathematical fallacy, there are some domains of knowledge for which it isn’t complete nonsense, and one of them was discussed at length by Buckminster Fuller. For example, if you are given three equally sized rods and asked to form a single equilateral triangle, the solution would be trivial.

What is the meaning of 1+1=4?

This is called a mathematical fallacy, and 1+1=4 is an extraneous solution resulting from our violation of the associative rules of multiplication – namely the fact that we divided by zero when we divided both sides by the quantity ‘a’ (line 5).

Can you divide by zero if a is equal to B?

But, you say, that’s not dividing by zero—it’s dividing by a – b. That’s true, but we started with the assumption that a is equal to b, which means that a – b is the same thing as zero! And while it’s perfectly fine to divide both sides of an equation by the same expression, it’s not fine to do that if the expression is zero.
