Rock on!

I like this calculator! Especially with where you can see your calculation and the answer! I may not know how to use programmer, subnets, matrix, or grapher, but the calculator itself is amazing! Although, I didn't see a couple things. I didn't see anything for fraction calculations. Also degree/minute/seconds calculations. I use that a lot to calculate time played on a game I have on the laptop called Farming Simulator 2013. I have another calculator that does these kinds of calculations, but it would be very nice to see these added in an update! That would make it a little more fun to calculate them! But great graphics and style!

Seriously I wasn't expecting such a good calculator with all of these features. Especially with only a $1 for the pro version. Worth it
