- Rewrite the expression using the rule that adding a negative number is equivalent to subtraction: \(132 - 15 - 10\).
- Subtract 15 from 132 to get 117.
- Subtract 10 from 117 to get 107.
- The final result is \(\boxed{107}\).
Explanation
- Understanding and Analyzing the Expression
The problem requires us to calculate the value of the expression \(132 + (-15) + (-10)\). In mathematics, adding a negative number is equivalent to subtracting its positive counterpart. Therefore, we can rewrite the expression as \(132 - 15 - 10\). We will perform these subtractions step by step.
- Performing the Calculation
We start by calculating the first part of the expression: \(132 - 15\). Performing the subtraction gives:
\[132 - 15 = 117\]
Next, we take the result and subtract the final number, which is 10:
\[117 - 10 = 107\]
Thus, the value of the entire expression is 107.
Examples
Imagine you have a savings account that starts with \$132. You withdraw \$15 for a small purchase and then withdraw another \$10 for a snack. To find out how much money is left in your account, you calculate \(132 - 15 - 10\). Arithmetic like this is essential for keeping track of your personal finances and ensuring that your daily transactions are calculated accurately.
