How do you multiply imaginary numbers?
How do you multiply imaginary numbers? (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. Watch out a lot more about it.
What are the values of imaginary numbers?
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. By definition, zero is considered to be both real and imaginary.
Can imaginary numbers be real numbers?
Yes, imaginary numbers are valid, first-class numbers just like real numbers. Human civilizations managed to make do without imaginary numbers for millennia, but at a certain level of scientific and technological development they become essential.
Can we compare real numbers and imaginary numbers?
• The square of a real number is non-negative, but the square of an imaginary number is negative. • Set of real numbers forms a complete totally ordered field whereas the set of imaginary numbers is neither complete nor ordered.

Imaginary Number i The most basic complex number is i, defined to be i = −1, commonly called an imaginary number. Any real multiple of i is also an imaginary number. Example 1 Simplify − 9 . We can separate − 9 as 9 −1. We can take the square root of 9, and write the square root of -1 as i. − 9 = 9 −1 = 3i

Complex numbers are represented in standard form as z = a + bi, where a is the real part and b is the imaginary part of the complex number z. With this form, a real num- ber is simply a + 0i and a pure imaginary number is 0 + bi. Standard form of a complex number is also called rectangular form.
