The Set of Numbers
• Natural Numbers
– The set of natural numbers contains
{1, 2, 3,…}
• Whole Numbers
– The set of whole numbers contains
{0, 1, 2, …}
• Integers
– The set of integers contains
{…, -3, -2, -1, 0, 1, 2, 3, …}
Set of Real Numbers, cont’d
• Rational Numbers –the set of all numbers that
can be expressed as a quotient of integers
• Irrational Numbers – the set of all numbers
that correspond to points on the number line
but that are not rational numbers. That is, an
irrational number is a number that cannot be
expressed as a quotient of integers.
• Real Numbers – is the set of all numbers each
of which correspond to a point on the number
line.
