other more general settings. Even and odd numbers have opposite parities, e.g., 22 (even number) and 13 (odd number) have opposite parities. In particular

(3⋅1001)2 ⋅ (22⋅1001 − 1) = 198585576189 would be an odd perfect number if only 22021 (= 192 ⋅ 61) were a prime number. The odd numbers with this property (they would

than a round number, e.g. $19.99 or £2.98. There is evidence that consumers tend to perceive just-below prices (also referred to as "odd prices") as being

that the total number of 1-bits in the string is even or odd. Accordingly, there are two variants of parity bits: even parity bit and odd parity bit. In

this article, we will assume this condition to hold true. If the number of points N is odd, say N=2K+1, applying the Lagrange formula for polynomial interpolation

{\displaystyle 2\times n/2} ⁠. Therefore, every prime number other than 2 is an odd number, and is called an odd prime. Similarly, when written in the usual decimal

square is also a centered octagonal number. Another property of a square number is that (except 0) it has an odd number of positive divisors, while other

(sixty-seven) is the natural number following 66 and preceding 68. It is an odd and prime number. 67 is: the 19th prime number (the next is 71). a Chen prime

is the natural number following 68 and preceding 70. An odd number and a composite number, 69 is divisible by 1, 3, 23 and 69. The number and its pictograph

or odd, one writes the permutation as a product of disjoint cycles. The permutation is odd if and only if this factorization contains an odd number of
