1. Secondary Math Essentials Chapter 1.1

2.  Classify the following numbers using one or more of the following terms:  Natural Number  Whole Number  Integer  Rational Number  Irrational Number 6 0 Natural Number Whole Number Integer Rational Number Whole NumberInteger Rational Number Irrational Number

3. Adding? Move to the right Subtracting? Move to the left 6-8= -2+5=-6-2= -2 3 -8

4.  Rules:  If the signs match, add numbers & keep the sign  Examples: ( - 3 ) + ( - 9 ) = ( - 1 ) + ( - 1 ) = 5 + 9 = Write this rule in your notes!!! ( - 9 ) + ( - 1 ) = -6 – 2 = 16 + 8 = -8 – 4 = -16 – 9 =

5.  Rules:  If the signs are different, subtract numbers & keep the sign of the bigger number  Examples: 3 + ( - 9 ) = ( - 1 ) + 1 = 5 - 19 = Write this rule in your notes!!! 9 – 15 = -6 + 2 = 16 - 8 = -8 + 6 =-25 + 6 =

6.  Try these on your own using the rules we wrote in our notes: -12 + 7 =7 – 8 = -6 + 12 =-8 – 6 = -10 – 7=18 – 41 =

7.  Two negatives right in a row create a positive  Examples: Write this rule in your notes!!! (-1) – (-40) = 10 + 3 – (-8) = 13 – (-29) = -8 – 4 = -10 – 15 =

8.  If the signs are the same:  If the signs are the different: add numbers & keep the sign subtract numbers & keep the sign of the bigger number Two negatives right in a row create a positive

9.  How many can you finish CORRECTLY in 2 minutes?  Graph results
