Just like logical operators, conditions also use true/false to make decisions. As you saw in the video, they do this with if/else statements.

• 3 = 3
Three is equal to three.

Still with me?  You can evaluate these kinds of expressions as either true or false.  You can also add them to if/else statements. Let's start with greater than:
