Integers are whole numbers that can be positive, negative or zero and do not contain decimal places. They can be visualized on a number line with arrows on both ends extending to infinity, where their position relative to one another indicates their size, with numbers to the right being greater than those to the left. The relations between integers can be stated by comparing their positions on the number line.

1. Integers
part 1

2. definition
An integer is a whole number (not a
fraction) that can be positive, negative, or
zero.
integers cannot have decimal places.
Integer can be visualized on a number
line:

3. What is a number line?
• A line with arrows on both ends that show
the integers with slash marks
• Arrows show the line goes to infinity in
both directions ( + and -)
• Uses a negative sign (-) with negative
numbers but no positive sign (+) with
positive numbers
• Zero is the origin and is neither negative
nor positive

4. The position of integer in
number line

5. State the relation between
two integers
Can be stated for every p,q integer apply:
 if p lies to the right of q so p>q
 If p lies to the left of q so p<q
