# Convention of a += operator in pseudo-code

I have to write some algorithm in pseudocode for a paper. For this I have the "$$\leftarrow$$" to assign a value.

$$x \leftarrow y^2$$

now I want to write a method which adds to the variable. In normal Python code I would write `x += 1` for this. Is there a style convention how to layout this in pseudo-code in a paper? I dont really like the redundance of $$x \leftarrow x+1$$.
