At the end of the 16th century, François Viète introduced the idea of representing known and unknown numbers by letters, nowadays called variables, and the idea of computing with them as if they were numbers—in order to obtain the result by a simple replacement.

Frangois Viète (Latin: Vieta), a great French mathematician, is credited with the invention of this system, and is therefore known as the "father of modern algebraic notation" [3, p. 268].

The person to popularize the use of π to signify the mathematical value was Euler. He also started the use of Σ for summations. Alternatively, Francois Viete was the first to use letters to represent unknowns. This in all likelihood led to the introduction of Greek letters when Latin characters ran out.

There were several systems for writing numbers in Greek; the most common form used in late classical era used omicron (either upper or lower case) to represent the value 70. More generally, the letter omicron is used to mark the fifteenth ordinal position in any Greek-alphabet marked list.

To some extent, however, the legend of the 6th Century BCE mathematician Pythagoras of Samos has become synonymous with the birth of Greek mathematics. Indeed, he is believed to have coined both the words "philosophy" ("love of wisdom") and "mathematics" ("that which is learned").

The original alphabet was developed by a Semitic people living in or near Egypt. * They based it on the idea developed by the Egyptians, but used their own specific symbols. It was quickly adopted by their neighbors and relatives to the east and north, the Canaanites, the Hebrews, and the Phoenicians.

Ƶ and ƶ are also used by mathematicians, scientists, and engineers as variants of Z and z in hand-written equations to avoid confusion with the numeral 2.

Integers. The letter (Z) is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity.

Etruscan. The Etruscan letter Z was derived from the Phoenician alphabet, most probably through the Greek alphabet used on the island of Ischia. In Etruscan, this letter may have represented /ts/.

According to many scholars, it was in Egypt that alphabetic writing developed between 1800 and 1900 BC. The origin was a Proto-Sinaitic (Proto-Canaanite) form of writing that was not very well known. About 700 years after, the Phoenicians developed an alphabet based on the earlier foundations.

The earliest form of the letter appears on the Moabite Stone, dating from the 9th century bce. Early Greek forms gave way to intermediate Greek and Latin renditions that were virtually identical to the modern B.

Gian Giorgio Trissino (1478–1550) was the first to explicitly distinguish I and J as representing separate sounds, in his Ɛpistola del Trissino de le lettere nuωvamente aggiunte ne la lingua italiana ("Trissino's epistle about the letters recently added in the Italian language") of 1524.

The letter Z is of uncertain origin. In a very early Semitic writing used in about 1500 bc on the Sinai Peninsula, there often appeared a sign (1) believed by some scholars to mean the same as the sign (2) which was developed beginning in about 1000 bc in Byblos and in other Phoenician and Canaanite centers.

The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.

Several civilisations developed positional notation independently, including the Babylonians, the Chinese and the Aztecs. By the 7th Century, Indian mathematicians had perfected a decimal (or base ten) positional system, which could represent any number with only ten unique symbols.

Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.

Did God create math? The short, unequivocal answer is yes. You can find an expanded answer in Colossians 1:16 : “For by Him all things were created, in heaven and on earth, visible and invisible…all things were created through Him and for Him.” The word 'all' includes math along with everything else God created.

Unlike a light bulb or a computer, mathematics isn't really an invention. It's really more of a discovery. Mathematics encompasses many different types of studies, so its discovery can't even be attributed to one person. Instead, mathematics developed slowly over thousands of years with the help of thousands of people!
