To simplify the expression \( 12 - 5 \cdot 127 \), follow these steps:
1. **Identify Operations**: The expression contains subtraction and multiplication. According to the order of operations (PEMDAS/BODMAS), you should perform the multiplication before the subtraction.
2. **Perform Multiplication**: Calculate \( 5 \cdot 127 \).
- This results in \( 5 \times 127 = 635 \).
3. **Subtraction**: Now substitute back into the expression. The expression becomes \( 12 - 635 \).
4. **Calculate the Result**: Now perform the subtraction:
- \( 12 - 635 = -623 \).
So, the simplified answer is \( -623 \).
