This document discusses integers and how to add and subtract them. It defines integers as whole numbers and their opposites, including positive numbers like 1, 2, 3 and their negative counterparts. It explains that integers can be plotted on a number line and how their position relative to zero determines if they are positive or negative. The document provides examples of how to add integers by keeping their sign positive if both numbers are the same sign or subtracting the numbers and keeping the sign of the larger integer if the signs are different. It also explains how to convert subtraction of integers into addition by changing the subtraction sign to addition and making the second number negative.

1. 0…-5,-4,-3,-2,-11,2,3,4,5...Get It!Got It! GREAT!Adding Integers The Positive and Negative of it All…

2. IntegersGet It! Got It! GREAT!What is an Integer?Integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5… and their opposite numbers less than zero: -1,-2,-3,-4,-5…Integer is 17Opposite is -17Integer is -8Opposite is 8Integer is 23Opposite is -23

3. IntegersIntegers on a Number LineNegative Integers are opposite whole numbers less than zero: -1,-2,-3,-4,-5…Positive Integers are whole numbers greater than zero: 1,2,3,4, 5…0…-5,-4,-3,-2,-11,2,3,4,5...

4. IntegersHow to add positive & positive integers Positive Integers are whole numbers greater than zero: 1,2,3,4, 5…35+

5. IntegersThey are BOTH positive Therefore… add numbersAndKEEP IT POSITIVE!35+12435678

6. IntegersHow to add negative & negative integers -35+Negative Integers are opposite whole numbers less than zero: -1,-2,-3,-4,-5…IntegersThey are BOTH negative Therefore… add numbersAndKEEP IT NEGATIVE!-3-5+-1-2-3-6-4-7-5-8

7. IntegersHow to add negative & positive integers -35+

8. IntegersNotice how positive and negatives are opposites going two different directions1-1

9. IntegersNotice how positive and negative touch ends or points but don’t point in the same direction. 00…-5,-4,-3,-2,-101,2,3,4,5...

10. IntegersPositive 1/negative-1cancel out to zero. 100As pernumber line-1Positive 1/positive 1& negative -1/negative -1follow the same direction and increase 2 or decrease -2.1+1= 2-1+ -1= -2

11. IntegersAdding negative & positive integers -35+

12. Integers-35+5-3=25 is bigger and positive so answer must be positive.12000Hint: Subtract both numbers and keep the sign of the bigger whole number.

13. IntegersSubtracting IntegersAdding and subtracting integers is almost identical. We convert the subtraction symbol to addition and give the following number its opposite sign.-2 - 3-2 + -3= -5Change – to + and opposite of 2 is -25 - 75 + -7= -2-2 – -8-2 + 8= 6Change – to + and opposite of 7 is -7Change – to + and opposite of -8 is 8
