Integers Add , Subtract, Multiply, Divide.

Positive + positive = positive Negative + Negative = Negative Ex1_ -7+2= -5 Ex2_ -5 – 11= -5 (+) +11= +16

Instructions on adding negative and positive integers
When adding a negative and a positive you always take the sign from the largest number.

Subtracting Negative & Positive Integers
Negative - Positive = Negative Positive - Negative = Positive Ex1_ = Ex2_ -16 (+) -8 = (+) -6= 49

Instructions on subtracting positive and negative integers
When subtracting a negative or a positive you always change the subtraction sign to an addition sign and then change the second # to a positive or negative & take the sign that is the largest.

Multiplying Positive & Negative Integers
Positive * Positive = Positive Negative * Negative = Positive Negative * Positive = Negative Positive * Negative = Negative When Multiplying negative & a negative it is always going to be a positive and when ever there are the same signs it will always be a positive.

Dividing Positive & Negative Integers
Positive / Positive = Positive Negative / Negative = Positive Negative / Positive = Negative Positive / Negative = Negative

Instructions on dividing negative & positive integers
When ever you divide a positive and a positive you get a positive and when you divide a negative and a negative you get a positive but when you divide a negative and a positive you get a negative..so therefore when you divide integers that got the same sign it’s a positive and when you divide integers that have different signs it’s a negative
