1 + 1 = 2
Any "proof" you see that claims otherwise is fallacious.
Edit: by dividing by zero.
Note: one plus one also equals window, zero (when in mod 1), and 11 (1&1)

Can you prove one plus one is equal to one?
One plus one does equal two. If you have one object, then bring in another object, you will have one more than what you started with. That would be two.
How do you prove ax5 plus bx4 plus cx3 plus dx2 plus ex plus f equals 0 is not solvable?
This is called the Abel-Ruffini theorem.
How do you prove by induction 1 plus 3 plus 32 plus 33 plus ... plus 3n plus 1?
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
How do you prove cot squared theta plus cos squared theta plus sin squared theta scs squared theta?
Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.
How do you prove tan x plus sin x equals 2 tan x?
This would be a real bear to prove, mainly because it's not true.
How do you prove that In a quadrilateral ABCD prove that AB plus BC plus CD plus DA 2( AC plus BD )?
You cannot prove it since it is not true for a general quadrilateral.
Can you prove one plus one is equal to one?
One plus one does equal two. If you have one object, then bring in another object, you will have one more than what you started with. That would be two.
Can you mathematically prove 9 plus 10 equals 21?
No you can not prove that 9 +10 = 21.
How do you prove if a is less than b then a plus c is less than b plus c?
I believe that's usually treated as an axiom, meaning you don't prove it.
How do you prove ax5 plus bx4 plus cx3 plus dx2 plus ex plus f equals 0 is not solvable?
This is called the Abel-Ruffini theorem.
How do you prove 1 plus 1 equal to 1?

If you start without a definition of one or two how do you prove that one plus one equals two?
a) Everyone knows what one and two are, so they will know 1 + 1 = 2 b) Assuming they do not know what one and two are, it will be impossible to explain to them 1 + 1 = 2, because these definitions are ESSENTIAL to prove 1 + 1 = 2.
How do you prove by induction 1 plus 3 plus 32 plus 33 plus ... plus 3n plus 1?
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
How would you prove 1 plus 1 equals 2?
Using a calculator
How do you prove cot squared theta plus cos squared theta plus sin squared theta scs squared theta?
Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.
Can someone prove that 2k2k plus 1-1 by induction?
To prove that 2k 2k plus 1-1 by induction is a step by step process. But the induction 2 is not equal to 2 to the power of 0 take away 1.
Delta H equals delta E plus delta nRT prove?
Yes
