This sentence was long and hard to absorb could it be broken in two and/or have the 'but' removed? I just found it hard to take in. Below is my attempt, which is probably not better.

The notation for the type-signature of a multi-argument function, can seem surprising. We will explain where it comes from when we get to function currying in the section called “Multi-argument functions”.

Context:

The notation for the type-signature of a multi-argument function may be a little surprising at first, but we'll explain where it comes from when we get to function currying in the section called “Multi-argument functions”. For the moment, think of the arrows as separating different arguments of the function, with the type after the final arrow being the return value. Thus, int -> int -> float describes a function that takes two int arguments and returns a float.
