Sometimes the biconditional in the statement of the phrase “if and only if” is shortened to simply “iff.”. Thus the statement “P if and only if Q” becomes “P iff Q.”. The phrase "if and only if" is used ...The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2. 3 Answers. The ⇒ notation means that if the function on the left hand side of the notation is true, then so is the function on the right hand side of the notation. So consider X ⇒ Y. This means that if X is true, then Y is also true. It is necessary to use this sometimes.

Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A". Good question! It is derived from the Latin word quadrare, which means "to square", which is what you do in quadratics. Though you may think it means something to do with four, this is not true, because it is simply referring to squaring (a square has four sides.)

In programming languages, q % p is the remainder of q divided by p. Mathematicians more commonly notate a similar operation as q ( mod p), except that q % p returns specifically an integer from { 0, 1, 2, …, p − 1 } whereas q ( mod p) technically returns an equivalence class r + p Z. Often ( mod p) has the same use however.10 mai 2007 ... do not represent the same thing or value. (The symbols != and <> are ... (Some writers use ≡ to mean congruence).
