    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 ...

    If each subtraction is replaced with addition of the opposite (additive inverse), then the associative and commutative laws of addition allow terms to be added in any order. The radical symbol ⁠ t {\displaystyle {\sqrt {\vphantom {t}}}} ⁠ is traditionally extended by a bar (called vinculum ) over the radicand (this avoids the need for ...
