Getting error trying to use functions to multiply numbers

[Yoriz]

Question 1
You could pass the function that return user input directly into the calculate function

calculate_result(get_user_input_1(), get_user_input_2())

note as your get_user_input functions are basically the same apart from the string that the user sees(also the numbering 1 & 2 is usually a telltale sign)
these should be changed into one function that takes the string as input.

def user_input(prompt):
    return input(prompt)

you can create constants for the user input prompts

PROMPT_1 = "Type a number: "
PROMPT_2 = "Type another number to multiply by your first number: "

and then the calculate_result call would be

calculate_result(user_input(PROMPT_1), user_input(PROMPT_2))

Then you see that your function is not actually adding anything to the built-in input
so you could remove the functions and just use

calculate_result(input(PROMPT_1), input(PROMPT_2))

Note you would also likely want to add to the user_input function to say validate the input and then the function would be worth having.

Question 2
When you don't use parentheses a function is not run, this is useful because then a function can be passed around to other functions and then called at another point.
