@. Complex Number:

Complex number is a number that comprises both a real part and an imaginary part.

#. It is expressed in the form: a + bi

 

a	a represent the real part.
b	b represent the imaginary part.
i	i is the imaginary unit.

 

@. Complex Number:  C

An imaginary number is a mathematical concept that extends the set of real number.

Such as:{  }

@. Real Number: R

Real numbers encompass both rational and irrational numbers.

They represent the complete continuum of numbers on the number line, including all possible function, decimal, and integers.

Such as:

@. Rational Number: Z

Rational numbers include integer number and fraction number.

Such as:               {-2, -1, 0, 1, 2} (Integer Number)

@. Irrational Number:

Irrational Numbers are real numbers that cannot be expressed as fraction.

Such as:

@. Integer Number:

Integer numbers are the whole numbers along with their negative counterparts.

Such as:{-2, -1, 0, 1, 2}

@. Fraction Number:

A fraction is a number that represents a part of a whole.

It is written in the form of two numbers separated by a line, where the number above the line is called the numerator, and the number below the line is called the denominator.

Such as:

@. Natural Number: N

Natural numbers also known as counting number, are set of positive integers.

Such as:{1, 2, 3, 4, 5, 6, 7, 8}

@. Whole Number:

Whole numbers include all the natural number with zero.

Such as:{0, 1, 2, 3, 4, 5, 6, 7, 8}
