1.1

Integers

	Definition

	Positive and negative whole numbers including \(0\).

Positive numbers:

Numbers written with the '\(+\)' sign or without any sign.
Examples: \(+12, 4, +7, 1\)
Positive integers are integers that have a value greater than \(0\).

Negative numbers:

Numbers written with the '\(-\)' sign.
Examples: \(-6, -2, -15, -27\)
Negative integers are integers that are lower than \(0\).

	Example

	Determine whether the following numbers is an integer. (i) \(\dfrac{7}{2}\) (ii) \(6.8\) (iii) \(-12\)

	(i) \(\dfrac{7}{2}\) is not an integer because it is a fraction. (ii) \(6.8\) is not an integer because it is a decimal. (iii) \(-12\) is an integer.

Integers on a number line:

On a number line, the numbers in the positive direction are always greater than the numbers in the negative direction.

Integers in order:

A positive number always has a larger value than a negative number.
