Math Tags

Math tags are a useful part of Denizen that, as the name implies, allows you to perform mathematical operations internally.

Here's the general syntax, with spaces for readability. (You shouldn't include spaces in your actual script. If you must, put it in "quotes")

<m: firstThing + secondThing> 
//Now, all together,
<m:firstThing+secondThing>

Of course, + isn't the only mathematical operator that can be used. You can also use:

Minus and Modulus: (- and %)

Divide and Multiply: (/ and *)
