Rules When multiplying and dividing integers
there are two rules:1. When multiplying or dividing integers that
have the SAME sign, the answer is POSITIVE.
Positive x positive = positive Negative x negative = positive
+7 x +12 = +84-6 x –5 = +30

Rules continued…Rule 2:
When multiplying or dividing integers whose signs are DIFFERENT, the answer will always be NEGATIVE.Positive x negative = negativeNegative x positive = negative
+8 x –4 = -32-5 x +7 = -35

Let’s Sing a Song!Multiplying Integers Song (sing to “Dead Bones” tune)
Verse 1 A negative times a negative is a, (um) positive A negative times a positive is a, (um) negativeA negative times a negative is a, (um) positive
These are the rules for signs.Verse 2
If you have the same signs, you get a positive, But if they’re different, you get a negative,
If you have the same signs, you get a positive,Yes, these are the rules for signs.

Let’s Practice!What sign would the answer have in front of the
integer???
-5 x -7 = ???
