Challenge: Fraction Calculator
I have built a site to teach math but I don't have enough time to build the math tools that I would like to. If you wish to help I will make posts about the tool I would like made. I will not be using the tool to make money. It will be placed on the site as free to use. Simply post a link to your code and the one with the most up votes wins. Make sure to display a name and email contact on your tool. The first challenge is to make a fraction calculator that takes fraction inputs and performs the operation of addition, subtraction, multiplication and division the result must be presented as either a mixed number fraction or a proper fraction. BONUS: There should be a button to convert from mixed number fraction to an improper fraction. You can only use html5, css3 and Javascript. You can also use any libraries or APIs you wish.
