complex number
This term is a technical mathematical designation used primarily in algebra, physics, and engineering. It describes a value that extends the one-dimensional real number line into a two-dimensional complex plane, allowing for the solution of equations that have no real roots, such as those involving the square root of a negative number.
In professional and academic discourse, the term is used with high precision. It is distinct from the word "complex" used as an adjective to mean "complicated"; here, "complex" refers specifically to the composition of real and imaginary components.
