The characterization as "a relation each thing bears to itself and to no other thing" is often criticized as circular ("no other thing"), [32] and around the 17th century, with the growth of modern logic, it became necessary to have a more concrete description of equality. In foundations of mathematics, especially mathematical logic [11] [33 ...
A function (which in mathematics is generally defined as mapping the elements of one set A to elements of another B) is called "A onto B" (instead of "A to B" or "A into B") only if it is surjective; it may even be said that "f is onto" (i. e. surjective). Not translatable (without circumlocutions) to some languages other than English.
An example of using Newton–Raphson method to solve numerically the equation f(x) = 0. In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign.

The introduction should say the following: In mathematics, equality means that the things are the same thing. If we write "x = y" or "x equals y", then x and y are the same thing. To say it another way, "x" and "y" are both names for the same thing. David Marcus 16:44, 12 October 2018 (UTC)
1. Between two numbers, either it is used instead of ≈ to mean "approximatively equal", or it means "has the same order of magnitude as". 2. Denotes the asymptotic equivalence of two functions or sequences. 3. Often used for denoting other types of similarity, for example, matrix similarity or similarity of geometric shapes. 4.
