Mathematics is about concepts not symbols. Greeks: used specific symbols for multiples of 10 or 100. Their interest in square and triangular number suggests that they may have represented numbers by patterns of dots. They wrote fractions is several ways. One was to write the numerator, followed by a primer, and then the denominator followed by a double prime. the denominator was written twice.
The ten symbols currently used today to denote decimal digits are referred as Hindu-Arabic numerals.
Brahmi system was similar to the Greek number symbolism except that it used special symbols rather than letters of the alphabet.
In positional notation, where the meaning of a symbol depends on its location, it is important to specify that location without ambiguity,
Aryabhata wrote on his book about an alphabetic system of numerals, arithmetical rules, solution methods for linear and quadratic equations, trigonometry and a very close approximation of pi.
Mahavira had in his book fractions, permutations and combinations, the solution of quadratic equations, Pythagorean triangled and an attempt to find the area and perimeter of an ellipse.

Lilavati included in his book, the method of casting out the nines, in which numbers are replaced by the sum of their digits to check calculations, it contained several rules for divisibility by 3,5,7 and 11. The role of zero as a number.
Bijaganita is about the solution of equations.
Siddhanta Siromani deals with trigonometry: sine tables and various trigonometric relations.
Due to the commercial trade form the Arabic to Europe many ideas as well as commerce were exchanged. Fibonacci introduced the Hindu-Arabic number symbols to Europe.
Simon Stevin combined the best of the Babylonian sexagesimal and invented a base 10, which are the decimals. He pointed out it's efficacy as a business tool: all computations that are met in business may be performed by integers alone without the aid of fractions.
The Chinese introduced a system of "counting rods" rather than the abacus. They laid the rod out in patterns to represent numbers.
Diophantus, said that all numbers had to be positive and ignored the negative numbers. But hindu mathematicians found the negative numbers very useful because they represented debts in negative numbers.
Computers represent number is binary (base 2) not decimal (base 10).
