Chapter 2, Problem 20E

Program Plan Intro

a.

Natural number:

• Natural number is actually a positive that is obtained by adding one to the number repeatedly.
• Natural numbers can be 1, 2, 3 and so on.
• All positive integers are natural numbers.

Negative number:

• Negative number is a number which is less than zero and is represented by a negative sign on the front.
• Negative number generally represents negative of a number.
• If the movement is from right, then it represents a positive number and if movement is from left, then it represents a negative number.
• Thus on a scale a negative number is used to represent the numbers that is less than zero.

Rational number:

• Rational number is a number that can be expressed as quotient of two integers.
• Rational numbers can be either positive, negative or zero.
• Rational numbers can be either greater than or less than or equal to zero. It can either be positive, negative or equal to zero.
• Rational numbers can be expressed as a fraction of two integers p and q represented by “$\frac{\text{p}}{\text{q}}$” where p is numerator and q is denominator.
