3What are Integers?Integers are whole numbers and their opposites. Ex.(0, 1, 2, 3, 4…)Integers consist of negative and positive numbers.Zero is neither negative nor positive.
4Positive Integers Integers that are greater than zero. They will always be to the right of the zero on the number line.
5Negative Integers Integers that are less than zero. They will always be to the left of the zero on the number line.
6Adding IntegersWhen adding integers with the same signs, add the two numbers and keep that sign.When adding integers with opposite signs, subtract the smaller number from the larger number and keep the sign of the larger number.
7Examples of Adding Integers (-7) + 8 = 115 + (-23) = -8(-11) + (-5) = -16Check out this site for more practiceAdding Integers
8Subtracting IntegersFirst change problem to addition. Remember the phrase ADD THE OPPOSITE!!! Change the subtraction symbol to addition and the number that follows becomes its opposite.Then, follow the rules for adding integers.Visit this site to get some practice with integers.Magic Squares Game
