Running the following, only the menu() function is run, none of the if/else block seems to work.

```
def menu():
    print('''
    1-addition
    2-subtraction
    3-multiplication
    4-devision
    ''')

import random

def multiplication_random(number1,number2):
    c=number1*number2
    return c
    num11 = random.randint (1,1000)
    num21 = random.randint (1,1000)
    print("these are going to be multiplied, they are random numbers:")

def devision_random(number1,number2):
    c=number1/number2
    return c
    num22 =random.randint (1,1000)
    num12 = num2 * random.randint (1,1000) 
    print("these are going to be devided, they are random numbers:")

def subtract_random(number1,number2):
    c=number1-number2
    return c
    num13 = random.randint (1,1000)
    num23 = random.randint (1,1000)
    print("these are going to be subtracted, they are random numbers:")

def add_random(number1,number2):
    c=number1+number2
    return c
    num14 = random.randint (1,1000)
    num24 = random.randint (1,1000)
    print("these are going to be added, they are random numbers:")

menu()

choice = input('pick a number from the menu')

if choice == 1:
    add_random(number1,number2)
    print(num14)
    print(num24)
    print(add_random(num11,num21))

elif choice == 2:
    subtract_random(number1,number2)
    print(num13)
    print(num23)
    print(subtract_random(num12,num22))

elif choice == 3:
    multiplication_random(number1,number2)
    print(num11)
    print(num21)
    print(multiplication_random(num13,num23))

elif choice == 4:
    devision_random(number1,number2)
    print(num12)
    print(num22)
    print(devision_random(num14,num24))
