Brief Description: Contradiction is a method of proof in mathematics. It can be used to prove, for example, the infinitude of primes (that there are infinite number of them), the irrationallity of square root of 2, and much more. How... (read more)

Given two coordinates in the usual x-y axes, let's suppose that they are denoted by (x1, y1) and (x2, y2), then the midpoint is simply the average of each of the x and y values: Midpoint = ( (x1+x2)/2 , (y1+y2)/2 ) In higher dimensions, the idea is... (read more)

Given two numbers a and b, the greatest common divisor can be found by prime factorising each number and then grouping together the common ones. Example 1: Find the highest common factor of a... (read more)

Short description: Factorisation is the decomposition of an expression into multiple products of ‘simpler’ terms. It has a wide range of uses. For example, it can be used for solving polynomial equations,... (read more)
