# math Function Y = Y + 2 where does this fit in math? [closed]

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.

The statement $Y=Y+2$ is false: if $Y=Y+2$, then $0=2$. It makes sense only as an assignment statement in some programming language, replacing the current value of $Y$ by value $2$ greater. –  Brian M. Scott Dec 11 '12 at 23:13
