The identity relation is an equivalence relation. Conversely, let R be an equivalence relation, and let us denote by x R the equivalence class of x, consisting of all elements z such that x R z. Then the relation x R y is equivalent with the equality x R = y R.
118 is the smallest number that can be expressed as four sums with the same product in this way. [2] Because of its expression as 118 = 3 5 − 5 3, it is a Leyland number of the second kind. [3] 118!! - 1 is a prime number, where !! denotes the double factorial (the product of even integers up to 118). [4]
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
To reduce confusion between the multiplication sign × and the common variable x, multiplication is also denoted by dot signs, [4] usually a middle-position dot (rarely period): . The middle dot notation or dot operator , encoded in Unicode as U+22C5 ⋅ DOT OPERATOR , is now standard in the United States and other countries .

The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. [1] In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the ...
