Evaluate the following arithmetic expression:
`35+12-18xx3-:6`

Answer

To evaluate the arithmetic expression \( 35 + 12 - 18 \times 3 \div 6 \), 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 expression**:
\[ 35 + 12 - 18 \times 3 \div 6 \]

2. **Perform the multiplication and division first**:
- Calculate \( 18 \times 3 \):
\[ 18 \times 3 = 54 \]
- Now the expression becomes:
\[ 35 + 12 - 54 \div 6 \]

3. **Next, perform the division**:
- Calculate \( 54 \div 6 \):
\[ 54 \div 6 = 9 \]
- Now the expression becomes:
\[ 35 + 12 - 9 \]

4. **Now perform the addition**:
- Calculate \( 35 + 12 \):
\[ 35 + 12 = 47 \]
- Now the expression becomes:
\[ 47 - 9 \]

5. **Finally, perform the subtraction**:
- Calculate \( 47 - 9 \):
\[ 47 - 9 = 38 \]

### Final Answer:
The final answer is \( 38 \).
