I can read and write integers and find the absolute value of a number.

Numbers like 5 and -8 are called integers. An integer is any number from the set {…-4, -3, -2, -1, 0, 1, 2, 3, 4,…} where … means continues without end.

Negative integers are integers less than zero. They are written with a – sign. Positive integers are integers greater than zero. They can be written with or without a + sign.

Graph – Integers can be graphed on a number line. To graph a point on the number line, draw a point on the line at its location. Absolute value – The absolute value of a number is the distance between the number and zero on a number line.

Write an integer for each situation. 1.) 6 degrees above normal 2.) 2 inches below normal

Graph the set of integers {4, -6, 0} on a number line. Hint: First, draw the a number line. Then draw a dot at the location of each integer.

What is the absolute value of -5? What is the absolute value of 5? Evaluate the following expressions. 1.) І -4 I 2.) I-5I – I 2 I
