  1. CHAPTER 2 SECTION1

  2. INTEGERS AND ABSOLUTE VALUE GOAL: compare and order integers, find the absolute value of an expression The INTEGERS are the set = {…,-3,-2,-1,0,1,2,3,…}

  3. Comparing integers: INEQUALITY SYMBOLS: > GREATER THAN < LESS THAN

  4. Examples: 12 □ -15 -34 □ -16 123 □ 125 54 □ 49 13 □ -13 46 □ 45 The humidity yesterday was 83% and today its 75%. Write an inequality statement for the humidity.

  5. Order integers: Given a set of integers, put them in order from least to greatest. 1. {9,3,5,1,0,12,8} 2. {-4,-12,0,-56,-23,-1} 3. {12,-9,10,4,-3,-7,0}

  6. Absolute value: Absolute value is the distance a point is from zero on a number line. Symbols 78 2. -13 3. -123 4. -9 + -12 11 -20 3 -5
