Muhammad ibn Musa al-Khwarizmi, best known by his formerly latinized name Algoritmi, which then originated the term algorithm, meaning a systematic set of rules used to solve a problem. He is the father and inventor of Algebra, which comes from part of the title of his book on solving equations. He designed the modern set of numerals what is known as the Arab Numerals based on angles.
"If a person had ethics and manners then he is = 1
If this person was beautiful then add a zero to the one = 10
If s/he had money, then add another zero = 100
If s/he had a good family and relatives, then add another zero = 1000
If you lose number 1 which is ethics and manners, the value of that person is lost and what remains are the zeros which have no value at all." - Al-Khwarezmi
