KIDS TRIVIA

Detailed explanation-1: -An expression is a first-class data element in the Maple language. In other words, expressions can be stored in data structures, passed as arguments to procedures, and manipulated in various ways; they are often used to represent mathematical objects.

Detailed explanation-2: -Maple uses I to represent one of the square roots of-1, with-I representing the other, for computations over the complex numbers. Arithmetic expressions involving I and other numeric constants are automatically evaluated. The evalc function can be used to symbolically manipulate complex-valued expressions.
