A complex number has a real part and imaginary part. In x+iy, the x is real and the iy is imaginary. In 3d, you can have x+iy+ik. Complex numbers produce amazing fractals.
A wise man said complex numbers are useless and to be avoided at all cost.

Is 2 and a half a complex number number?
2 ½ is called a mixed number (a whole number and a fraction), not complex.Complex number means there can be real and/or imaginary parts to a number. Without confusing you though, complex numbers include all of the real numbers (which include all fractions and mixed numbers).
How do you divide complex numbers?
When dividing complex numbers you must:Write the problem in fractional formRationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator.You must remember that a complex number times its conjugate will give a real number.a complex number 2+2i. the conjugate to this is 2-i1. Multiply both together gives a real number.(2+2i)(2-2i) = 4 -4i + 4i + (-4i2) (and as i2 = -1) = 8To divide a complex number by a real number simply divide the real parts by the divisor.(8+4i)/2 = (4+2i)To divide a real number by a complex number.1. make a fraction of the expression 8/(2+2i)2. multiply by 1. express 1 as a fraction of the divisor's conjunction. 8/(2+2i)*(2-2i)/(2-2i)3. multiply numerator by numerator and denominator by denominator.(16-16i)/84. and simplify 2-2i
Is 2 a complex number?
No, it is not.
What is the complex number of z 2 - Ii?
The complex number of the equation z = x + iy is x.
What is the usefulness of the conjugate and its effect on other complex numbers?
The conjugate of a complex number is the same number (but the imaginary part has opposite sign). e.g.: A=[5i - 2] --> A*=[-5i - 2] Graphically, as you change the sign, you also change the direction of that vector. The conjugate it's used to solve operations with complex numbers. When a complex number is multiplied by its conjugate, the product is a real number. e.g.: 5/(2-i) --> then you multiply and divide by the complex conjugate (2+i) and get the following: 5(2+i)/(2-i)(2+i)=(10+5i)/5=2+i
How you mean complex number in your life?
A complex number, in my life, is a number which is composed of two parts: one part which is a real number and the other which is imaginary. It can be represented by a point in a coordinate plane.
What is a non real complex number?
Complex numbers are written in the form (a+bi), where i is the square root of -1.A real number does not have any reference to i in it.A non real complex number is going to be a complex number with a non-zero value for b, so any number that requires you to write the number i is going to be an answer to your question.2+2i for example. (2 plus 2 times i)
What is the complex number of its distance for the origin in the complex plane?
This is called the magnitude. It can be found (for a complex number a + bi) as:(where a & b are both real numbers and i is the imaginary unit)sqrt(a^2 + b^2)
What is the real part of the complex number -2i?
It is 0. The number is wholly imaginary.
Is a computer a complex machine?
Yes it has many parts all doing different functions.
Is every complex number a real number?
A complex number z has two parts - a real part and an imaginary part - and is of the form:z := x + iywherex and y are real numbersi represents √-1, that is i2 = -1.("x" is the real part, "iy" is the imaginary part)As x and y are real numbers, they can be any real number including 0.If x = 0, the resulting complex number z is of the form "iy" and is totally imaginary;if y = 0, the resulting complex number z is of the form "x" and is totally real.Thus real numbers are a subset of complex numbers, that is every real number is a complex number, but not every complex number is a real number.yes
Is the product of a complex number and its conjugate a real number?
Yes. If you multiply X + iY by X - iY you get X2 + Y2. The imaginary parts cancel out.
What number is not part of the rational number system?
An irrational number, an imaginary number, a complex number, a quaternion.
What Numbers that can not be written as a ratio of 2 integers?
Some examples are an irrational number, an imaginary number, a complex number.

Are there irrational numbers that are not real numbers?
An imaginary number i is defined as the square root of -1, so if you have something like the square root of -2, the answer would be i root 2, and that would be considered an irrational non-real number.* * * * *Not quite. The fact that irrational coefficients can be used, in conjunction with i to create complex numbers (or parts of complex numbers) does not alter the fact that all irrational numbers are real numbers.
How do you find the argument of the complex number -2-i?
arg(-2-i) = sqrt[22 + 12] = sqrt(5)
