Plimpton 322 is a Babylonian clay tablet, believed to have been written around 1800 BC, that contains a mathematical table written in cuneiform script.Each row of the table relates to a Pythagorean triple, that is, a triple of integers (,,) that satisfies the Pythagorean theorem, + =, the rule that equates the sum of the squares of the legs of a right triangle to the square of the hypotenuse.
The repeating decimal commonly written as 0.999... represents exactly the same quantity as the number one. Despite having the appearance of representing a smaller number, 0.999... is a symbol for the number 1 in exactly the same way that 0.333... is an equivalent notation for the number represented by the fraction 1 ⁄ 3.

Section 74 of the Act empowered boards to create a by-law and to table it before Parliament to make attendance compulsory unless there was an excuse, such as sickness, living more than three miles from a school or having been certified as reaching a certain standard of education. In 1873, 40% of the population lived in compulsory attendance ...
The user may estimate the location of the decimal point in the result by mentally interpolating between labeled graduations. Scientific notation is used to track the decimal point for more precise calculations. Addition and subtraction steps in a calculation are generally done mentally or on paper, not on the slide rule.
Many non-integral values, such as decimal 0.2, have an infinite place-value representation in binary (.001100110011...) but have a finite place-value in binary-coded decimal (0.0010). Consequently, a system based on binary-coded decimal representations of decimal fractions avoids errors representing and calculating such values.
The Platypus has had precisely the same time to evolve as the rest of mammals, even if it does not resemble our concestor 15. On its large bill, it has evolved a highly developed form of electroreception served by 40,000 electric sensors, and 60,000 mechanical push rods , which aid it in search of crustaceans in the mud.
The scores typically range between 7 and 10 in Rio and São Paulo, and the points are further subdivided into decimal fractions in Rio and 25 hundredths in São Paulo. [68] In Rio, all the marks given by all the jurors are valid, while in São Paulo the lowest score for each category is eliminated .
