'''Solution'''
In Fōrmulæ, a function is just a named lambda expression, and a function call is just a lambda application.
The following is a simple definition of a lambda expression:

When a lambda application is called with the same number of arguments, the result is the habitual:

However, if a less number of parameters is applied, currying is performed. Notice that the result is another lambda expression.

Because the result is a lambda expression, it can be used in a lambda application, so we must get the same result:
