PrimeQ (Built-in Mathematica Symbol)

PrimeQ[expr] yields True if expr is a prime number, and yields False otherwise.

Range (Built-in Mathematica Symbol)

Range[i_max] generates the list {1, 2, ..., i_max}. Range[i_min, i_max] generates the list {i_min, ..., i_max}. Range[i_min, i_max, di] uses step di.

SeedRandom (Built-in Mathematica Symbol)

SeedRandom[n] resets the pseudorandom generator, using n as a seed. SeedRandom[] resets the generator, using as a seed the time of day and certain attributes of the current ...

Slot (Built-in Mathematica Symbol)

# represents the first argument supplied to a pure function. # n represents the n\[Null]\[Null]^th argument.

StringJoin (Built-in Mathematica Symbol)

"s_1" <> "s_2" <> ..., StringJoin["s_1", "s_2", ...], or StringJoin[{"s_1", "s_2", ...}] yields a string consisting of a concatenation of the s_i.

Throw (Built-in Mathematica Symbol)

Throw[value] stops evaluation and returns value as the value of the nearest enclosing Catch. Throw[value, tag] is caught only by Catch[expr, form] where form is a pattern ...

Times (Built-in Mathematica Symbol)

x*y*z, x*y*z, or x y z represents a product of terms.

ToExpression (Built-in Mathematica Symbol)

ToExpression[input] gives the expression obtained by interpreting strings or boxes as Mathematica input. ToExpression[input, form] uses interpretation rules corresponding to ...

TrigFactor (Built-in Mathematica Symbol)

TrigFactor[expr] factors trigonometric functions in expr.

While (Built-in Mathematica Symbol)

While[test, body] evaluates test, then body, repetitively, until test first fails to give True.
