Answer

To evaluate the expression `21 + 7 + 7 - 11 - 14`, we can follow these steps:

### Step 1: Perform the addition first
We start by adding the numbers together:
- First, add the first two numbers:
\( 21 + 7 = 28 \)

- Next, add the result to the next number:
\( 28 + 7 = 35 \)

### Step 2: Perform the subtraction
Now, we will subtract the numbers:
- First, we can combine the subtraction terms:
\( 11 + 14 = 25 \)

- Now, subtract this sum from the previous result:
\( 35 - 25 = 10 \)

### Final Answer
Thus, the final result of the evaluation is:
