Step by step solution

01

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.
02

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 \(-10\).
03

Check the Final Result

Finally check the result obtained \(-10\). This is the simplified result of the initial arithmetic problem.
