Splash Screen Slide 2 Main Idea/Vocabulary integer negative integer positive integer graph absolute value Read and write integers, and find the absolute value of a number. Slide 3 Example 1 Write an integer for the following situation. a total rainfall of 2 inches below normal Answer: Because it represents below normal, the integer is 2. Write Integers for Real-Life Situations Slide 4 Example 2 Write an integer for the following situation. a seasonal snowfall of 3 inches above normal Answer: Because it represents above normal, the integer is +3 or 3. Write Integers for Real-Life Situations Slide 5 1.A 2.B 3.C 4.D Example 2 A.5 B.5 C.27 D.none of the above Write an integer for the following situation. a total snowfall of 5 inches above normal Slide 6 1.A 2.B 3.C 4.D Example 1 A.4 B.4 C.36 D.none of the above Write an integer for the following situation. an average monthly temperature of 4 degrees below normal Slide 7 Example 3 Graph Integers Graph the set of integers 1, 3, 2 on a number line. Draw a number line. Then draw a dot at the location of each integer. Slide 8 1.A 2.B 3.C 4.D Example 3 Graph the set of integers 2, 1, 4 on a number line. A. B. C. D. Slide 9 KC 1 Slide 10 Example 4 Evaluate Expressions Evaluate the expression |5|. On the number line, the graph of 5 is 5 units from 0. Answer: So, |5| = 5. Slide 11 Example 4 Evaluate Expressions Evaluate the expression |3|. On the number line, the graph of 3 is 3 units from 0. Answer: So, |3| = 3. 3 units right Slide 12 1.A 2.B 3.C 4.D Example 4 A.9 B.0 C.9 D.81 Evaluate the expression |9|. Slide 13 1.A 2.B 3.C 4.D Example 4 A.7 B.0 C.-7 D.49 Evaluate the expression |7|. Slide 14 Example 5 Evaluate the expression |4| |3|. Treat the absolute value like parenthesis (PEMDAS). DO THEM FIRST!!! |4| |3| |4| = 4, |3| = 3 4 3 1Subtract. Answer: 1 Evaluate Expressions Slide 15 Example 5 Evaluate the expression |-8| + |5|. Treat the absolute value like parenthesis (PEMDAS). DO THEM FIRST!!! |-8| + |5| |-8| = 8, |5| = 5 8 + 5 13Add Answer: 1 Evaluate Expressions Slide 16 1.A 2.B 3.C 4.D Example 5 A.3 B.3 C.13 D.40 Evaluate the expression |8| |5|.
