Yes. It's like writing instructions for how to make a cup of tea. You
might want to put in one spoon of sugar, someone else might prefer
two. On the instructions, you simply write "Add sugar to taste", and
that's what this is drawing analogy with. The PEP, as then written,
would happily accept all of these:

x = y*2+z*3
x = y*2 + z*3
x = y * 2 + z * 3

but would advise against:

x =y*2  +  z* 3
