Let x be the number of cocks, y be the number of hens, and z be the number of chicks, then the problem is to find x, y and z satisfying the following equations: x + y +z = 100 5x + 3y + z/3 = 100. Obviously, only non-negative integer values are acceptable. Expressing y and z in terms of x we get y = 25 − (7/4)x z = 75 + (3/4)x
The Battle of Semarang (Indonesian: Pertempuran Semarang), in Indonesia also known as Pertempuran Lima Hari (Five Days' Battle) [8] was a clash between Japanese forces of the Sixteenth Army and Indonesian forces consisting of People's Security Agency personnel and pemuda in October 1945 at the city of Semarang, Central Java.

Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
Lucas numbers have L 1 = 1, L 2 = 3, and L n = L n−1 + L n−2. Primefree sequences use the Fibonacci recursion with other starting points to generate sequences in which all numbers are composite. Letting a number be a linear function (other than the sum) of the 2 preceding numbers. The Pell numbers have P n = 2P n−1 + P n−2.
[2] [3] Historically, the concept of a proof and its associated mathematical rigour first appeared in Greek mathematics , most notably in Euclid 's Elements . [ 4 ] Since its beginning, mathematics was primarily divided into geometry and arithmetic (the manipulation of natural numbers and fractions ), until the 16th and 17th centuries, when ...
Tulus composed a single, entitled "Lekas", which was used on the soundtrack for the Indonesian movie, 3 Nafas Likas (2014). In mid 2015, Tulus created a song with Ran , an Indonesian music group, for that will be used in an ad campaign for Listerine .
[1] [2] Data may represent abstract ideas or concrete measurements. [3] Data are commonly used in scientific research , economics , and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index ), unemployment rates , literacy rates, and census data.
