- Fraction - Wikipedia
Fractions can be used to represent ratios and division [1] Thus the fraction 3 4 can be used to represent the ratio 3:4 (the ratio of the part to the whole), and the division 3 ÷ 4 (three divided by four) We can also write negative fractions, which represent the opposite of a positive fraction
- Irreducible fraction - Wikipedia
An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered) [1]
- List of types of numbers - Wikipedia
These include improper fractions as well as mixed numbers Continued fraction: An expression obtained through an iterative process of representing a number as the sum of its integer part and the reciprocal of another number, then writing this other number as the sum of its integer part and another reciprocal, and so on
- Pells equation - Wikipedia
A general development of solutions of Pell's equation in terms of continued fractions of can be presented, as the solutions x and y are approximates to the square root of n and thus are a special case of continued fraction approximations for quadratic irrationals
- Square root - Wikipedia
Notation for the (principal) square root of x For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 52 (5 squared) In mathematics, a square root of a number x is a number y such that ; in other words, a number y whose square (the result of multiplying the number by itself, or ) is x [1] For example, 4 and −4 are square roots of 16 because Every nonnegative real number x has a unique
- Square (algebra) - Wikipedia
