I'm bored, so here's a mathematical puzzle.
1=1
a=b
a^2=ab
a^2-b^2=ab-b^2
(a+b)(a-b)=a(a-b)
a+b=a
a+a=a
2a=a
2=1???

What is the objective of this puzzle? to solve for a and b?
If so, I think they both equal 0.

The objective is to figure out how the equation works. I made purposeful mistake in the equation to get the answer. The goal is to figure out what was the error I made.

it all makes sense until the
a+b=a
a+a=a
2a=a
...or am I the one not making sense?

a+b=a
That equation becomes a+a=a because in the beginning of the puzzle, I stated that a=b, so I can substitute the variables for one another. If you want the solution, I'll message it to you.
