Y = Y + 2
Then
Y = Y - 2
Can I go to... 2Y/Y = 2 ?
I can't remember what this belongs to in mathematics...
Thank you for any help.

You have written an equation with no solutions: the statement that $Y = Y + 2$ is satisfied by no $Y$. In other words, as a statement, it's false. In your title, you mention the word "function." A function is something that takes in something, and spits out something else. For example, $f(x) = x + 2$ is a function: if you input $x$, it spits out $x+2$. I've heard people liken functions to machines: you stick stuff in and they crank stuff out. What you've written is not a function. This also means that it is neither part of the "functions" tag nor the "functional equations" tag - unless you happen to mean that $Y$ is a function of something like $t$. In that case, the statement is still false. |

This is a false equation. You can go from $Y=Y+2$ to $0=2$ |
