  1. -3 -2 -1 0 +1 +2 +3 Integers

  2. What are integers? A: An integer is a whole number that is above or below zero. Positive Integers: A positive integer is a whole number above zero. Example: 0+4=4 Negative Integers: A negative integer is a whole number below zero. Example: 0-4=(-4)

  3. When do people use integers?

  4. Absolute value: Absolute value is the distance between a number and zero. The absolute value always possite. Opposites: Opposites are the same distance from 0 on the number line but are on opposite sides of 0. Examples: Opposite of 4 = -4 |-4|=4 Hint: |n| stands for absolute value.

  5. Comparing and OrderingIntegers -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +10 Remember negative numbers are less than 0 and positive are more than 0. So positive integers are ALWAYS greater than negative integers. The further a negative integer from 0 the lesser it is. The further a positive integer from 0 the greater it is. Order from least to greatest Compare -52_8 A: < |-8|_8 A: = -4_-7 A: > 9,-4,10,1,6,-7 A: -7,-4,1,6,9,10 2,3,-9,0,5,-13 A: -13,-9,0,2,3,5 6,-8,9,0,11,-1 A: -8,-1,0,6,9,11

  6. Adding Integers 4+(-6)=? Adding Negative Integers Add as if the integers were positive. The sum will ALWAYS be negative!!! Adding a Negative to a Positive Subtract the numbers add the sign of the largest absolute value. Examples (-9)+(-1)=-10 4+(-12)=-8 10+(-7)=3 |-5|+(-2)=3
