### How to interpret your Personal Polynomial

Here’s a short video giving a very quick overview of how it all works.

**The Math Behind The Scenes: Do you want to know more about how these polynomials are created?** Here’s a longer explanation so you can dive deeper in the math behind it all!

If you prefer to read, here’s a little description:

Say your names is JAMES. (How coincidental! That is my name!)

The Personal Polynomial for James is

####
P(x) = 8324 x^{4} – 49712 x^{3} + 414124 x^{2} – 346312 x + 164.

And how does this spell James?

Well, put in the value 1 for **x**, work out the arithmetic, and see that that value 10 results. And what is the tenth letter of the alphabet? It’s J!

Put in the value 2 for **x**, work out the arithmetic, and see that the value 1 results. And what is the first letter of the alphabet? It’s A!

Keep doing this and see JAMES appear.

P(1) | = 10 | = J |

P(2) | = 1 | = a |

P(3) | = 13 | = m |

P(4) | = 5 | = e |

P(5) | = 19 | = s |

Amaze your friends and family, and share your polynomial with the world!
