## An elementary mathematical theorem in hypertext form

Below you will find a little theorem about square numbers and triangle
numbers. Instead of a proof, I included a large number of hints; so feel
encouraged to play with the terms, to find out their properties and to
prove your own conjectures.

When you have no idea which step to make next, or if you want to
compare your solutions with mine, simply click on the statement in
question to get a hint. Some statements may also hide multiple hints;
you can get them one after another by clicking repeatedly on the
original statement. When you click on some hint, you will often get
a more detailed hint for it, if there is one. Simply start by clicking
on the definition to get the first problem; then click more carefully,
if you want to develop your own ideas without having been influenced
too much by my thoughts.

In order to limit the number of WEB pages to be prepared, I decided
to close automatically all hints not lying directly on the path to
the last requested hint, but I hope to circumvent this restriction in
a future version.

At this point, I want to express my thanks to my colleague Tobias
Wirnsberger, who formulated and proved a first a similar theorem,
and thereby inspired me to prepare this presentation in the WEB.

Enjoy!
