Summary: Multiplying and Dividing Integers
Key Concepts
- Multiplication of Signed Numbers
- To determine the sign of the product of two signed numbers:
Same Signs Product Two positives Two negatives Positive Positive Different Signs Product Positive • negative Negative • positive Negative Negative
- To determine the sign of the product of two signed numbers:
- Division of Signed Numbers
- To determine the sign of the quotient of two signed numbers:
Same Signs Quotient Two positives Two negatives Positive Positive Different Signs Quotient Positive • negative Negative • Positive Negative Negative
- To determine the sign of the quotient of two signed numbers:
- Multiplication by [latex]-1[/latex]
- Multiplying a number by [latex]-1[/latex] gives its opposite: [latex]-1(a)=-a[/latex]
- Division by [latex]-1[/latex]
- Dividing a number by [latex]-1[/latex] gives its opposite: [latex]a\div(-1)=-a[/latex]
