Define: Gematria

Gematria (Rabbinic Hebrew גימטריה gēmaṭriyā), is believed to have been formed from a metathesis of the Greek word grammateia ("play upon letters"), from gramma (letter) and literally means 'that which is written'[1], and is a system of assigning numerical value to an alphabet. It is extant in English since the 17th century from translations of works by Giovanni Pico della Mirandola. Although ostensibly derived from Greek, it is largely used in Jewish texts of Tanakh and Talmud, notably in those associated with the Kabbalah.

Some identify two forms of gematria: the "revealed" form, which is prevalent in many several hermeneutic methods found throughout Rabbinic literature, and the "mystical" form, a largely Kabbalistic practice

Translation - simply:
Gematria is the assignment of number to letter. Numerology is the study of meaning in numbers as they relate to other numbers (such as birth dates) and/or letters(words). Digit summing is a practice of Numerology which can also be called 'reduction', where digits are added until a single digit is reached. Some numbers are not reduced to single digits and these are called Master Numbers. To reduce a single 'number' further would be to break it into it's binary digits. Binary is the representation of letter and/or number character in the form of ones and zeros. To reduce the binary would then be to group by ones and zeros.

Fibonacci is a growth pattern that basically equates to 'past plus current, equals next'.

A = 1

I use the English alphabet because it's the only language I currently know. Other forms of Gematria can be found and some links will be provided soon... for now, this is what it is.

As a reminder on Numerology Digit Summing... it means to add until a single digit is reached. So, back to that alphabet...
