 Adding and Subtracting Integer Extra Practice    https://learnzillion.com/lesson_plans/4790-subtract-integers-using-number-lines/ Check the file manager tab for extra notes! Integer and Absolute Value Notes    1) Integers are the set of whole numbers and their opposite. No fractions or decimals!  Examples:  9, -1, -2, 2, 19, -12, 3    Non- Examples: 1.2, -.3 -1/2, .4/ -.6987   2)    The opposite of a number is the  same  number but with the  different  sign. Example one: The opposite of 3 is -3. The opposite of -3 is 3.  Example opposite of -6 is 6.      3) The opposite of the opposite of a number is the original number. It can be illustrated as follows: −(−n) =n The  double  negatives cancel each other out. "Bye Negative, Hello Positve"    a)    -(-2) = 2  b)     -(-3) = 3   c)     opposite of opposite of 4: The expression is:    -(-4)          Simplified: 4 (double negative makes a positive)      d)      opposite of opposite of 5          1)  I start with 5         2)   the opposite is -5       3)   the opposite of that is 5      Absolute Value  the distance (spaces)  away from zero on a number line  (count the spaces not the lines on a number line) "Absolute Value is ALWAYS Absolutely Positive"   Example One: Find the absolute value of |-3|. I know that this is still only 3 spaces away from zero on a number line. The answer is still positive 3. I also know for absolute value only the answers will always be positive.   Example Two:  |3| I know this is still postive three because it is three spaces away from zero on the number line.   Example Three:   |-4|  + -(-5) 4 +  5  (absolute value of -4, which becomes 4) (The opposite of opposite of -5, which becomes 5 because a double negative makes a positve.)   = 9 Box and Whisker Plot Notes    Box and Whisker Plots 9 , 15 , 19 , 5 , 20 , 15• First things first order my data from Least to Greatest 5, 9, 15, 15, 19, 20• Put your hands up (Five things to create a Box and Whisker Plot) 1. Mrs. Hurst- Minimum Tell Mrs. Hurst (Whisper) - Mrs. Hurst the minimum is the number with the lowest value in my data Minimum: 5 2. Mrs. Lantrip - Maximum Tell Mrs. Lantrip (High Pitch Voice) - Mrs. Lantrip the maximum is the number with the highest value in my data Maximum: 203. Mrs. Hill - Median Tell Mrs. Hill (Serious Voice )- Mrs. Hill I got to find my median-Median- The number in the middle when they’re all lined up from the least to the most -Two in the middle so I find the mean - I think can I have two medians absolutely NOT!   Median- 15 [15+15= 30 30 / 2 (divide by the numbers of numbers I added) = 15 ]5,9,15,{15} 15,19,20 4. Mrs. Murdock - Lower Quartile Tell Mrs. Murdock (Low Pitch Voice) - Mrs. Murdock the lower Quartile is the median of my lower half Lower Quartile: 9 Lower half: 5, 9, 155. Mr. Sartain - Upper QuartileTell Mr. Sartain (Southern Accent) - Mr. Sartain, the upper quartile is the median of my upper halfUpper Quartile- 19 Upper half: 15, 19, 20  Midpoint Review (1st Nine Weeks):   Midpoint Review (1st Nine Weeks): Review Factors      Example: How many factors does 40 have?                    What are all of the factors of 40?                   Exponents      1.

How can I isolate it.  I know that 100x means 100 multiplied by x  and if I am trying to get x by its self, I need to think how can I reverse multiplication?  I can do the opposite operation or the inverse? The opposite of multiplication is division.   4. So I divide 100x by 100                  100x  1400=   _____               100   5. Whatever I do to one side I do to the other         1400          100x          ___       =   _____     100             100       6. 14 = x    7. 10% of 140 is 14   28) What is 10% of 130?     29)   ) What is 25% of 24?       30) 80 percent of what number is 20?
