150 BC — Jain mathematicians in India write the “Sthananga Sutra”, which contains work on the theory of numbers, arithmetical operations, geometry, operations with fractions, simple equations, cubic equations, quartic equations, and permutations and combinations. 50 BC — Indian numerals, the first positional notation base-10 numeral ...
A multiplication of a 10-digit number by a d-digit number (for d up to 10) took d+4 cycles, so the multiplication of a 10-digit number by 10-digit number took 14 cycles, or 2,800 microseconds—a rate of 357 per second. If one of the numbers had fewer than 10 digits, the operation was faster.
As of July 2024, π has been calculated to 202 trillion decimal digits. The last 100 decimal digits of the latest world record computation are: [1] Graph showing how the record precision of numerical approximations to pi measured in decimal places (depicted on a logarithmic scale), evolved in human history.
Orders of magnitude (data) An order of magnitude is usually a factor of ten. Thus, four orders of magnitude is a factor of 10,000 or 10 4 . This article presents a list of multiples, sorted by orders of magnitude, for units of information measured in bits and bytes . The byte is a common unit of measurement of information ( kilobyte, kibibyte ...

Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. [ 4] Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the ...
68 is a Perrin number. [1] It has an aliquot sum of 58 within an aliquot sequence of two composite numbers (68, 58, 32, 31, 1 ,0) to the Prime in the 31-aliquot tree. It is the largest known number to be the sum of two primes in exactly two different ways: 68 = 7 + 61 = 31 + 37. [2] All higher even numbers that have been checked are the sum of ...
The decimal numeral system (also called the base-ten positional numeral system and denary / ˈdiːnəri / [ 1] or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers ( decimal fractions) of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system ...
