Think of external names as parameter names that you only use when you call a function
so when i reference the arguments inside my function I use "A" and "B" but when i call my function I pass in a "Value" and a "Divisor"
func getRemainder(value a: Int, divisor b: Int) -> Int {
return a%b
}
let result = getRemainder(value: 10, divisor: 3)
