I don't consider myself good at maths or physics, so that's why I'm asking you.

The other day I saw this formula:

? = c+m => int. = -| ? | = ?+m

I don't know what ?,c,m and int. stand for , but I'm sure it was written like that.
Does anyone know what this formula is from?

(I heard somebody say that it was wrong cuz' the result was negative, but he was not talking about the (-|?|))
