Solve the following expressions:
`7 xx 3 + 8 - 2`

Answer

To solve the expression `7 xx 3 + 8 - 2`, we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

### Step-by-Step Solution:

1. **Identify the operations**: The expression consists of multiplication, addition, and subtraction: `7 xx 3 + 8 - 2`.

2. **Perform multiplication first**:
- Calculate `7 xx 3`.
- \( 7 \times 3 = 21 \).

Now the expression simplifies to:
\[ 21 + 8 - 2 \]

3. **Next, perform addition**:
- Calculate `21 + 8`.
- \( 21 + 8 = 29 \).

Now the expression simplifies to:
\[ 29 - 2 \]

4. **Finally, perform subtraction**:
- Calculate `29 - 2`.
- \( 29 - 2 = 27 \).

Thus, the final answer is:
\[ \text{The result is } 27. \]
