# How do i convert this equation into the node editor?

How do I make this in the node editor? I don't get how to go around y=(-x)

• Hello :). If you don't mind me asking, what are such equations in the node editor used for? I have honestly no idea. Feb 9 '20 at 9:29

It's best to be quite explicit with your bracketing.. In this example, when I didn't bracket the unary minus on x, the negative was applied to the whole expression, rather than binding to the variable. This is expected Python.. but maybe not obvious.
