The document discusses the number line and integers. It defines a number line as having equal distances marked off from a starting point of usually 0, with arrowheads indicating the line continues infinitely in both directions. The set of numbers used on the number line is called the set of integers, which includes natural numbers, whole numbers, and negative numbers arranged in order from left to right.

Integers and the Number Line Bob Guilbert
Constructing a Number Line A number line is drawn by choosing a starting position, usually 0, and marking off equal distance from that point
Although only a portion of the number line is shown, the arrowheads indicate that the line and the set of numbers continue
The set of numbers used on the number line is called the set of integers This set can be written {¡­, -3, -2, -1, 0, 1, 2, 3, ¡­}
The number line is made up of 3 sets of numbers Natural numbers 1, 2, 3, 4, ¡­ Whole numbers 0, 1, 3, 4, ¡­ Integers ¡­, -2, -1, 0, 1, 2, ¡­
We can use a Venn Diagram to represent thee 3 sets of numbers and their relationship to one another
You should not include the number 0 You should not include numbers less than 0 (negative numbers) You should not include the number 6 or any higher
Positive numbers move to the right Negative numbers move to the left + 3 + (-8) = -5
