Evaluate the following arithmetic expressions:
`19-4+52-:4xx3`

Answer

To evaluate the arithmetic expression \( 19 - 4 + 52 \div 4 \times 3 \), we will follow the BODMAS/BIDMAS rule, which stands for Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

### Step-by-Step Solution:

1. **Identify the Expression**:
\[ 19 - 4 + 52 \div 4 \times 3 \]

2. **Perform Division First**:
- Calculate \( 52 \div 4 \):
\[ 52 \div 4 = 13 \]
- Now, substitute back into the expression:
\[ 19 - 4 + 13 \times 3 \]

3. **Perform Multiplication Next**:
- Calculate \( 13 \times 3 \):
\[ 13 \times 3 = 39 \]
- Now, substitute back into the expression:
\[ 19 - 4 + 39 \]

4. **Perform Addition and Subtraction from Left to Right**:
- First, calculate \( 19 - 4 \):
\[ 19 - 4 = 15 \]
- Now, substitute back into the expression:
\[ 15 + 39 \]
- Finally, calculate \( 15 + 39 \):
\[ 15 + 39 = 54 \]

5. **Final Result**:
\[ 54 \]

### Summary of Steps:
1. Identify the expression.
2. Perform division.
