Well there you go, good point.
I didn't really like it being an operator myself. But I can see having a
math.tolerance class being useful.

Perhaps a more versatile operator would be to introduce a +- operator
that would return an object with an __eq__ method that checks for equality
in the tolerance i.e
a == b +- 0.5
This is already valid syntax, because unary minus is a thing. So this is
currently parsed as "a == b + (-0.5)".
Reversing it to use -+ won't work because unary plus is also a thing.
A little bit out of the box, but what about:
a == b +/- 0.5
...or even:
a == b +or- 0.5
Is "math.isclose(a, b, abs_tol=0.5)" really so hard to use?
