Multiplying and Dividing Integers
Grade 7 · Math · Operations with Rational Numbers · Ontario, Canada
Lesson Summary
Understand the sign rules for multiplying and dividing positive and negative numbers.
Explanation
When you multiply or divide two integers, the sign of the result depends on the signs of the numbers. If both signs match (both positive or both negative), the answer is positive. If the signs are different, the answer is negative. These rules apply to any number of factors: an even count of negative factors gives a positive product, while an odd count gives a negative product.
