 * addition (`+`)
 * subtraction (`-`)
+* increment (`{pp}`)
+* decrement (`--`)
 * multiplication (`*`)
 * division (`/`)
 * modulus (`%`)
 * exponential power (`^`)
 
+[NOTE]
+====
+The increment and decrement operators can be used with either prefix (`{pp}A`, `--A`) or
+postfix (`A{pp}`, `A--`) notation with variables or properties that can be written to.

 The following example shows the mathematical operators in use:
