Real Number System

The Real Number System includes all the numbers that can be found on the number line, including rational and irrational numbers.

Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Irrational numbers are numbers that cannot be expressed as a simple fraction; they have non-repeating, non-terminating decimal expansions.

Natural numbers are the set of positive integers starting from 1 (1, 2, 3, ...).

Whole numbers are all natural numbers including zero (0, 1, 2, 3, ...).

Integers are whole numbers that can be positive, negative, or zero (-3, -2, -1, 0, 1, 2, 3, ...).

No, -14 is not a natural number; natural numbers are always positive.

17/10 is a rational number.

3 is a natural number, whole number, integer, rational number, and real number.

False. Not every rational number is an integer; for example, 1/2 is rational but not an integer.
