Question
Simplify: \(-9-11+7-(-3) .\) (Section 1.6, Example 3)
Step-by-Step Solution
Verified Answer
-10
1Step 1: Identify the Numbers and Operations
In this problem, there are several numbers: -9, -11, 7 and -3. The problem asks to perform the operations of subtraction and addition on these numbers. It's important to note that subtracting a negative number is the same as adding its positive equivalent.
2Step 2: Apply the Operations in Correct Order
To solve this problem, carry out the operations from left to right. First, calculate \(-9 - 11\) to get \(-20\). Then add 7 to \(-20\) to get \(-13\). Finally, subtract \(-3\) from \(-13\), which is equivalent to adding 3 to get the result \(-10\).
3Step 3: Check the Final Result
Finally check the result obtained \(-10\). This is the simplified result of the initial arithmetic problem.
