What if that calculator knew your name? What if it carried on a conversation with you, and asked you questions? You'd probably remember it a little better Maybe even make a point of using it whenever you needed to crack an equation But you know what? You could build your own one-of-a-kind calculator. All you need is Java. Java is a very powerful, yet easy to learn language. It's absolutely FREE and it's EVERYWHERE...
