2+2 = 22

Now would be a good time to do some experiments with variables. The goal is to help you learn a thing or two. It may seem kinda stoobie now, but you're going to be using these basic concepts non-stop in the future.

Let's start by adding two variables together: valueA and valueB This is going to allow for some fun!

We haven't set the valueA or valueB variables, so you might assume when we add them together the answer is going to equal zero (Nothing plus Nothing is Nothing, right?).

Aha! NaN stands for Not A Number, and it's an error we will (unfortunately) come across on occassion. We're trying to add two undefined variables together. You see, nothing plus nothing really is nothing, and zero is NOT nothing! In fact, zero is a really important number! For those of you who got in arguments with math teachers because you couldn't understand this concept, go back and apologize.

Let's define those variables right now. Set both valueA and valueB variables with a Value of 2, then move those declarations to the top of the script using the Move the selected action(s) up button:

OK, now that the we have defined valueA and ValueB, test the results:

What! Remember how your grade school teacher laughed at you for insisting 2+2=22? It turns out you were just in the wrong class!

The ability to string together numbers like this might come in handy in the future, but right now we want to do a real calculation. The key word in that last sentence is string. The Values for valueA and valueB are registering as strings, because they are enclosed by a set of quotation marks. You remember how to omit those quotation marks using Script Assist:

OK, now check your work:

Finally, two plus two once again equals four.
