Abstract: This page presents mathematics diversions, which are basically just
math problems of varying difficulty, which one can try to solve for fun or for
testing one's math skills, or for learning new methods and concepts.


Disclaimer: Many of the following problems were taken from SATs or old
Olympiad tests. My alternative solutions may not follow Olympiad rules, however.
The techniques I use may not be fit for use in Olympiads or entrance exams or the like.
I believe that it's good to see alternative solutions to better fill out one's
mathematical abililties. Four decades ago, I quipped that one cannot truly
understand a theorem until one is able to prove it in essentially two different ways.
It's meant to be a thought-provoking claim, perhaps containing a morsel of truth.


This problem (#1) is found on the YouTube channel PreMath, from December 25, 2021.
My solution here is a little different from that given by the presenter. Statement of the problem:

that given by the presenter.

Statement of the problem: Find a solution for a,b,c given the the system of equations as follows:


The presenter's solution is perfectly good, and perhaps the shortest. However, my solution
will approach the problem from the standpoint of symmetry. One can find my solution to this

Presenter: Soul Institution

This has been one of the most revealing problems on the nature
of my using the unipodal algebra to solve these 'olympiad'
problems. I proved a simple but important lemma. Additionally,
I added some unipodal heuristics for consideration.

Given the relation \begin{equation} \sqrt{x}+\sqrt{x+1}+\sqrt{x+2} = \sqrt{x+7}\,, \end{equation} find the values of $x$.

Solution to this problem.
