For example, 1 / 4 , 5 / 6 , and −101 / 100 are all irreducible fractions. On the other hand, 2 / 4 is reducible since it is equal in value to 1 / 2 , and the numerator of 1 / 2 is less than the numerator of 2 / 4 . A fraction that is reducible can be reduced by dividing both the numerator ...

In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator.
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 2 , − 8 5 , −8 5 , and 8 −5 .
Now, 93 / 43 = 2 + 7 / 43 ; the remaining fractional part, 7 / 43 , is the reciprocal of 43 / 7 , and 43 / 7 is around 6.1429. Use 6 as an approximation for this to obtain 2 + 1 / 6 as an approximation for 93 / 43 and 4 + 1 / 2 + 1 / 6 , about 4.4615, as the third approximation.
A Karnaugh map (KM or K-map) is a diagram that can be used to simplify a Boolean algebra expression. Maurice Karnaugh introduced it in 1953 [1][2] as a refinement of Edward W. Veitch 's 1952 Veitch chart, [3][4] which itself was a rediscovery of Allan Marquand 's 1881 logical diagram[5][6] (aka. Marquand diagram[4]).
th root. In mathematics, an nth root of a number x is a number r (the root) which, when raised to the power of the positive integer n, yields x: The integer n is called the index or degree, and the number x of which the root is taken is the radicand. A root of degree 2 is called a square root and a root of degree 3, a cube root.
List of Runge–Kutta methods. Runge–Kutta methods are methods for the numerical solution of the ordinary differential equation. Explicit Runge–Kutta methods take the form. Stages for implicit methods of s stages take the more general form, with the solution to be found over all s. {\displaystyle k_ {i}=f\left (t_ {n}+c_ {i}h,y_ {n}+h\sum ...
