Multiplication table from 1 to 10 drawn to scale with the upper-right half labeled with prime factorisations. In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system.
For many years, the fields of quantum mechanics and computer science formed distinct academic communities. [2] Modern quantum theory developed in the 1920s to explain the wave–particle duality observed at atomic scales, [3] and digital computers emerged in the following decades to replace human computers for tedious calculations.

In mathematics, a semiprime is a natural number that is the product of exactly two prime numbers.The two primes in the product may equal each other, so the semiprimes include the squares of prime numbers.
The following formulas can be used to calculate the volumes of solute (V solute) and solvent (V solvent) to be used: [1] = = where V total is the desired total volume, and F is the desired dilution factor number (the number in the position of F if expressed as "1/F dilution factor" or "xF dilution"). However, some solutions and mixtures take up ...
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.The number π appears in many formulae across mathematics and physics.
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
The X Factor is a British reality television music competition, and part of the global X Factor franchise created by Simon Cowell.Premiering on 4 September 2004, it was produced by Fremantle's British entertainment company, Thames (Talkback Thames until 2011), and Cowell's production company Syco Entertainment for ITV, [2] as well as simulcast on Virgin Media One in Ireland.
In mathematics, an irreducible polynomial is, roughly speaking, a polynomial that cannot be factored into the product of two non-constant polynomials.The property of irreducibility depends on the nature of the coefficients that are accepted for the possible factors, that is, the ring to which the coefficients of the polynomial and its possible factors are supposed to belong.
