What is a non-real solution?

A non-real solution is a solution to a math equation, where the equation has the root of a negative number, which cannot be found using only real numbers - which are numbers that can be defined along a single axis. (0 and 1.2 and -1000 and pi and the square root of 2 are all real numbers that I can be put on an axis relative to each other. )

What is a nonreal complex number?

A nonreal complex number (often just called a nonreal number) is a complex number which, when written in the form of a + bi, the b is NOT 0. As the name implies, all numbers that are not real numbers are nonreal complex numbers. An imaginary number is a nonreal number which, when written in the a + bi form, the a IS 0.

What are complex numbered solutions?

Complex numbered solutions are non-real solutions to a math problem. A complex number has more information than a real number, and sometimes is the only way to describe a solution. A quadratic polynomial has two roots. These roots are often real-valued but sometimes they are complex numbers, i.e. non-real solutions.

How to use complex numbers calculator?

Complex numbers calculator can add, subtract, multiply, or dividing imaginary numbers. In short, we can use an expression as z = x + iy, where “x” is the real part and “iy” is the imaginary part. When performing simple operations on complex numbers, it is helpful to think of them as vectors.
