Frequently Asked Questions

The original sale presentation for MathRoomBuddy sounded familiar.

Since MathRoomBuddy's name is similar to the amazing invention called the Bathroom Buddy in the movie Gremlins, the sales pitch is an homage to the sales pitch used in the beginning of the movie. Here is the original description:

Well friends, you do have a lot of interesting data here, but there’s one thing you don’t have.

And what’s that?

Well, let me show you. I got it right here. I’m an inventor. I made this, the Mathroom Buddy. The invention of the century, friends. It eliminates the need to carry heavy computers and things when you travel.

You got yourself floating point. You got yourself hexadecimal. You got yourself signed decimal, you got unsigned decimal. You got all of these at once. You got yourself a bunch of math functions.

This is going to revolutionize math.

Now, let’s just say, for the sake of argument, that you’re on a bus or a plane or a train. You forgot to convert your data. You got yourself a bad case of bad data representation. Now, what do you do?

No problem, friend. All you do is, you take your phone out, and you push this button...

BZZZ!

That’s no problem. That’s absolutely no problem. Cleans up easily.
