-The following examples shows how easy this class is to use. 
-
 **Example #1**. Formula: `(8+(10*(3-5)^2))/4.8`
 
 ``` php
 $formula = new FormulaParser('(8+(10*(3-5)^2))/4.8', 'en', 4);
-$result = $formula->getResult(); // will return array(0=>'done', 1=>10)
+$result = $formula->getResult(); // array(0=>'done', 1=>10)
 ```
 
 **Example #2**. Formula: `sqrt(x^y) / log(exp(pi))`, and x = 4, y = 8.
 
 ``` php
 $formula = new FormulaParser('sqrt(x^y) / log(exp(pi))', 'en', 4);
