Arithmetic/Complex: Difference between revisions

{{task|Arithmetic operations}}A '''[[wp:Complex number|complex number]]''' is a number which can be written as "a + b*i" (sometimes shown as "b + a*i") where a and b are real numbers and [[wp:Imaginary_unit|i]] is the square root of -1. Typically, complex numbers are represented as a pair of real numbers called the "imaginary part" and "real part", where the imaginary part is the number to be multiplied by i.
