Yeah, you copy what I wrote into a file and save it as add.py or whatever you want to call it.

With Python installed you open up Command then change the directory to where you saved the file

cd C:\Users\MW_Dream\Desktop

Then type in python add.py

Now when you copy spaced numbers into Command then press [Enter] you should receive the answer, lol.
