Remember the difference between the asigment operator and comparison operators.

print(“Hello my friend”)

print (“I will be your Calculator”)

print (“Firstly, What would you like to do?”)

choice = input(str(“Add, Subtract, Multiply or Divide?”))

if choice == (“add”):

addition1 = input(int(“Enter a number you would like to use”))

addition2 = input(int(“Enter the number you would like to add”))

print (addition1 + addition2)

now it is saying this : Traceback (most recent call last): File “python”, line 6, in <module> ValueError: invalid literal for int() with base 10: ‘Enter a number you would like to use’

You must get the input first, then you convert it to int. Otherwise you’re trying to convert the string “Enter a number you would like to use” to int.

int(input("Enter a number you would like to use"))

I bossed it!!!

print(“Hello my friend”)
print (“I will be your Calculator”)
print (“Firstly, What would you like to do?”)
choice = input(str(“Add, Subtract, Multiply or Divide?”))
if choice == (“add”):
addition1 = input("Enter a number you would like to use: ")
addition2 = input("Enter the number you would like to add: ")
print (int(addition1) + int(addition2))
elif choice == (“subtract”):
subtract1 = input("Enter a number you would like to use: ")
subtract2 = input("Enter a number you would like to subtract: ")
print (int(subtract1) - int(subtract2))
elif choice == (“multiply”):
multiply1 = input("Enter a number you would like to use: ")
multiply2 = input("Enter a number you would like to Multiply by: ")
print (int(multiply1) * int(multiply2))
elif choice == input(“divide”):
divide1 = input("Enter a number you would like to use: ")
divide2 = input("Enter a number you would like to divide by: ")
print (int(divide1) / int(divide2))
print (“Thank you for using me today, have a nice week!”)

also, does anyone know how I could prehaps make it a loop to see if they wanted to do another math task
