We can think of numbers being on a number line: These numbers are all positive numbers.
The number line can also continue on past 0: These new numbers are negative numbers.
We can use our number lines to work out the sums which include negative numbers. We start at -3 First we locate -3 on the number line.
We can use our number lines to work out the sums which include negative numbers. We start at -3
We can use our number lines to work out the sums which include negative numbers. We start at -3 Next we count on 5 places to the right. After 5 jumps we arrive at 2

EXAMPLE 1 Apply the distributive property
POSITIVE AND NEGATIVE NUMBERS
Integers: Comparing and Ordering EQ How do we compare and order rational numbers?
Multiplying Integers. Warm Up 1.9 x 3 =5. 6 x 9 = 2.7 x 10 =6. 10 x 23 = 3.9 x 8 =7. 9 x 9 = 4.15 x 10 =8. 10 x 20 =
Adjusting numbers in a problem in a problem to make to make mental math easier easier.
ADDING INTEGERS Positive + Positive = Positive Positive + Positive = Positive ( +3) + (+2) = +5 ( +3) + (+2) = +5 When a number is positive, you do not.
Rules of Integers. Positive numbers are numbers that are above zero. Negative numbers are numbers below zero.
Multiplying Positive & Negative Numbers. -6 x –4 = =
1-7 Multiplying and Dividing Integers Steps: Multiply or divide the regular way Figure out the sign of the answer Rules for Multiplying and Dividing: a.
Step one: Convert the number you’re converting into a number between 1 and 10 by moving the decimal either to the left or to the right. Examples: 45,000.
Additive Inverse: Two numbers whose sum is 0 are additive inverses of one another. Example: 3/4 and – 3/4 are additive inverses of one another because.
Objective: Students will add integers using models and rules (11-3).
