How to use it:

1. First you need to reference jQuery library and the jQuery formula plugin into the html page.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="jquery.formula.js"></script>

2. Create two input fields with the data-variavel attribute to accept the values provided by your users.

<input type="text" data-variavel="field1">
<input type="text" data-variavel="field2">

3. Create an input field that will output the result based on the formula defined in the data-formula attribute.

<input type="text" data-formula="#field1# * #field2#">
