What am I doing wrong? Can't call earlier functions

def addition(num1, num2):
    answerAdd=num1+num2
    print(answerAdd)
def subtraction(num1, num2):
    answerSub=num1-num2
    print(answerSub)
def main():
    num1=int(input('Enter the first number: '))
    num2=int(input('Enter the second number: '))
    print(addition, subtraction)
main()

I’ve tried renaming the call function and can’t get it to return the arithmetic,.

>Solution :

A couple of problems:

1. print and return are not interchangeable. When you need your function to return a value you use return, when you merely need it to print something than use print. Your first two functions should be returning the values they calculate so that your main() function can print() them.

2. When calling your functions you have to give them values for the arguments you defined. Your addition and subtraction functions both have two arguments.

def addition(num1, num2):
    answerAdd=num1+num2
    #Problem 1: changed to `return`
    return answerAdd

def subtraction(num1, num2):
    answerSub=num1-num2
    #Problem 1: changed to `return`
    return answerSub

def main():
    num1=int(input('Enter the first number: '))
    num2=int(input('Enter the second number: '))
    #Problem 2: changed to send `num1` and `num2` as arguments to both functions
    print(addition(num1, num2), subtraction(num1, num2))

main()
