When using operators, there are certain things that would make your code much easier to read. Note: Bad style isn’t wrong, but if you're working or showing your code to someone else, trying to make it easily understandable to that person would be great.
Good style = Easily readable code.
a += 1; a = 5 - 1; a++;
Bad style = A programmer wanting to burn all of your existence in the project (Metaphorically).
a+=1; a=5 -1; a ++;
It may be tempting to cram a lot of operators into one line (“I personally love one liners.” - Matthew (The guy making this)). However, it may make your code a bit confusing.
a += b++ * --a % 50;
It may be a little hard for another programmer to know what the heck you wrote. So, it would be much better to break the code into separate lines.

a += b; --a; a %= 50; b--;
