A unit fraction is a common fraction with a numerator of 1 (e.g., 1 / 7 ). Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. 1 / 8 = 1 / 2 3 .
The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as a bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because ...
That is, fractions aren't difficult to compare if the numerator is 1 (e.g., 1 ⁄ 2 is larger than 1 ⁄ 3, which in turn is larger than 1 ⁄ 4). However, comparisons become more difficult when both numerators and denominators are mixed: 3 ⁄ 4 is larger than 5 ⁄ 7 , which in turn is larger than 2 ⁄ 3 , though this cannot be determined by ...
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
Note that if n 2 is the closest perfect square to the desired square x and d = x - n 2 is their difference, it is more convenient to express this approximation in the form of mixed fraction as . Thus, in the previous example, the square root of 15 is 4 − 1 8 . {\displaystyle 4{\tfrac {-1}{8}}.}
Half-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
The Apple Computer 1 (Apple-1 [a]), later known predominantly as the Apple I (written with a Roman numeral), [b] is an 8-bit motherboard-only personal computer designed by Steve Wozniak [5] [6] and released by the Apple Computer Company (now Apple Inc.) in 1976.
