# Complex Numbers

Complex numbers are numbers of the form a + ⅈb, where a and b are real and ⅈ is the imaginary unit. They arise in many areas of mathematics, including algebra, calculus, analysis and the study of special functions, and across a wide range of scientific and engineering disciplines. Oftentimes, they form connections between fields, for example with Euler's formula, which relates imaginary numbers to trigonometry and exponentiation. Use Wolfram|Alpha’s power and computational understanding to work with complex numbers, as well as the larger area of complex analysis, and to express them in different forms.

Do computations with complex numbers, from basic arithmetic to finding roots and solving equations.
