I'm learning about f# and I understand you don't need to use parentheses when calling a function. Ex let addOne arg1 = arg1 + 1 addOne 1 vs this.GetType() Why do I have to use parentheses on the second function?

When to use parentheses when calling a function in f#?

I'm learning about f# and I understand you don't need to use parentheses when calling a function.

let addOne arg1 =
    arg1 + 1

addOne 1

this.GetType()

Why do I have to use parentheses on the second function?
