Algebra 2 operations with complex numbers worksheet answers

A complex number is a combination of a Real Number and an Imaginary Number, written as a + bi (where a and/or b may equal zero). (a and b are real numbers and i is the imaginary unit) • If we have a + bi with a = 0, we have 0 + bi which gives bi, a purely imaginary number.

(x + yi) u = xu + yu i. In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0.
