In mathematics, like terms are summands in a sum that differ only by a numerical factor. [1] Like terms can be regrouped by adding their coefficients. Typically, in a polynomial expression , like terms are those that contain the same variables to the same powers , possibly with different coefficients .
This following list features abbreviated names of mathematical functions, function-like operators and other mathematical terminology. This list is limited to abbreviations of two or more letters (excluding number sets). The capitalization of some of these abbreviations is not standardized – different authors might use different capitalizations.
Visual proof of the Pythagorean identity: for any angle , the point (,) = (, ) lies on the unit circle, which satisfies the equation + =.Thus, + =. In mathematics, an identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B (which might contain some variables) produce the same value for all values of the variables ...
The term was coined when variables began to be used for sets and mathematical structures. onto 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 ...
Domain-specific terms must be recategorized into the corresponding mathematical domain. If the domain is unclear, but reasonably believed to exist, it is better to put the page into the root category:mathematics, where it will have a better chance of spotting and classification.

In mathematics, a constant term ... The number 3 is a constant term. [1] After like terms are combined, an algebraic expression will have at most one constant term ...
Aristotle also thought that quantity alone does not distinguish mathematics from sciences like physics; in his view, abstraction and studying quantity as a property "separable in thought" from real instances set mathematics apart. [5] Auguste Comte's definition tried to explain the role of mathematics in coordinating phenomena in all other ...
Reflexivity: for every a, one has a = a.; Symmetry: for every a and b, if a = b, then b = a.; Transitivity: for every a, b, and c, if a = b and b = c, then a = c. [7] [8]Substitution: Informally, this just means that if a = b, then a can replace b in any mathematical expression or formula without changing its meaning.
