- The division of a negative number by a positive number, \(-24 \div 8\), yields \(-3\).
- The product of two negative numbers, \(-2 \times (-7)\), yields \(14\).
- The final answers are \(\boxed{-3}\) and \(\boxed{14}\).
Explanation
- Analyzing the Problem
We are asked to evaluate two mathematical expressions involving integers: \(-24 \div 8\) and \(-2 \times (-7)\). The first expression is a division of a negative number by a positive number, while the second expression is a multiplication of two negative numbers. We will follow standard arithmetic rules for signs.
- Evaluating the First Expression
For the expression \(-24 \div 8\), we note that when dividing a negative number by a positive number, the result is negative. We divide the absolute values: \(| -24 | \div | 8 | = 24 \div 8 = 3\). Applying the negative sign gives \(-3\). So, \(-24 \div 8 = -3\).
- Evaluating the Second Expression
For the expression \(-2 \times (-7)\), we note that when multiplying two negative numbers, the result is positive. We multiply the absolute values: \(| -2 | \times | -7 | = 2 \times 7 = 14\). Thus, \(-2 \times (-7) = 14\).
- Conclusion
Based on our analysis, we have evaluated both expressions:
- \(-24 \div 8 = -3\)
- \(-2 \times (-7) = 14\)
The final results are \(-3\) and \(14\).
Examples
In everyday life, these basic operations are useful for managing budgets. For example, if you have a debt of \$24 spread over 8 payments, your monthly change is @@MATH_TOKEN_19@@ dollars. Conversely, if you have two charges of \$7 each canceled (e.g., refunds), the total effect is \(-2 \times (-7) = 14\) dollars added back to your balance. Mastering signs is crucial for tracking financial transactions correctly.
