### Section 1.3 integers absolute value (math)

1. 1. Section 1.3 Integers andAbsolute Value<br />
2. 2. Integers<br />Integers are zero, positive and negative whole numbers<br />Which of the following is not an integer?<br />5 0 -7.25 π<br />-2 9 305 -17<br />-12.5 -1/2 n 0<br />0.5 4/2 16/4 901<br />
3. 3. Categorize the following words in the Positive or Negative column of your paper:<br />Above<br />Below<br />Deposit<br />Down<br />Earn<br />Gain<br />Plus<br />Lose<br />Minus<br />Remove<br />Spend<br />Up<br />Win<br />
4. 4. Graphing Integers on the Number Line<br />Creative a number line like the one below and graph the points with the following coordinates: <br />-8 10 0<br />7 -5<br />
5. 5. Inequalities<br />Inequalities compares two different numbers or quantities. They contain symbols like <br /> < > ≤ ≥<br />< Less Than<br />> Greater Than<br />≤ Less Than or Equal To<br />≥ Greater Than or Equal To<br />
6. 6. Make the following sentence true by applying <br />< , > or =<br />12 _ 6 -18 _ 18 -14 _ -50<br />-12 _ 6 -200 _ -200 <br />13 _ -13 -350 _ 35 7+ 3 _ 9<br />
7. 7. Absolute Value<br />Pay EXTRA attention to this:<br />The Absolute Value of a number is the distance the number is from 0 on the number line.<br />
8. 8. For example:<br />Ι7Ι = 7 <br />Ι1Ι = 1<br />Ι-5Ι = 5<br />Ι3Ι + Ι4Ι <br />3 + 4 = 7<br />I-3I + I-4I <br />3 + 4 = 7<br />6 + I-3I<br />6 + 3 = 9<br />
9. 9. Evaluate the follow expressions if <br />x = -4 and y = 6<br />3 + IxI<br />IyI + IxI<br />x + IyI<br />7IxI<br />3IxIIyI <br />
