Python is very strongly typed too, so I don't really see how
maths is different.

Yes, but he has to remember what types are associated with
the variables -- nothing at their point of use indicates that.
Likewise, the reader of a Python program has to remember what
type of object each name is expected to be bound to. If he
can remember that, he will know what all the operators do.
