\[Rule]
(Mathematica Character Name) Unicode: F522. Alias: Esc -> Esc. Infix operator with built-in evaluation rules. x y is by default interpreted as x->y or Rule[x,y]. x y z groups as x (y z). ...
Rule
(Built-in Mathematica Symbol) lhs -> rhs or lhs -> rhs represents a rule that transforms lhs to rhs.
NumberSigns is an option for NumberForm and related functions which gives strings to use as signs for negative and positive numbers.
Root
(Built-in Mathematica Symbol) Root[f, k] represents the exact k\[Null]^th root of the polynomial equation f[x] == 0. Root[{f, x_0}] represents the exact root of the general equation f[x] == 0 near x = ...
lhs :> rhs or lhs :> rhs represents a rule that transforms lhs to rhs, evaluating rhs only after the rule is used.
Sign
(Built-in Mathematica Symbol) Sign[x] gives -1, 0, or 1 depending on whether x is negative, zero, or positive.
You may find it useful to use one or more rules with an expression several times. Mathematica provides functions that let you iterate when using rules with expressions. In ...
Since many functions in Mathematica give solutions in the form of rules, you need to be able to use these rules to explore and interpret your results. Although many of the ...
With its convenient symbolic representation of algebraic numbers, Mathematica's state-of-the-art algebraic number theory capabilities provide a concrete implementation of one ...
Rules
(Mathematica Guide) Everything that Mathematica does can be thought of as derived from its ability to apply general transformation rules to arbitrary symbolic expressions. The Mathematica ...
