I have a message to you all that this has a secret number. To do that, type "derp" for the 1st number and do the same thing on 2nd number and see what happens! You just click the plus. It would do that, but it would result in a bat flying; and the pluses forever turn into Easter eggs and 0/0 = Infinity
In this piece of this calculator, I hope you have an Easter egg in this app. Wait! Don't think of something when you're scrolling down to read that... so there is an Easter egg, Whenever you click on the plus, and you write rush on the first question, and then you write e on the second question the song rush e will play.
