create a score from multiple variables

[rfarmenta]

I have 5 binary yes/no variables that assess knowledge. I want to combine those 5 variables to indicate if they answered the questions correctly. What is the best way to do this, so for instance.

If they answered all 5 correct then their score would be 5, if they answered 4 then it would be 4, and so on...the score can be any combination of correct answers. Any help is greatly appreciated.

How you determine whether the awnswer is correct or not?

I have made it so the correct answer is always equal to 1 for ease.

add them up?

new_variable=sum(var1, var2, var3, var4, var5);

That works, that just seemed too simple I guess. Thank you for your help.
