What is the value of the expression 12 - (2 + 3) + 5?

Explanation:
To determine the value of the expression 12 - (2 + 3) + 5, it's essential to follow the order of operations, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). 1. **Evaluate the expression within the parentheses first**: The expression (2 + 3) simplifies to 5. 2. **Substitute this back into the main expression**: You can now rewrite the expression as 12 - 5 + 5. 3. **Proceed with left to right calculations**: First, you subtract 5 from 12, resulting in 7. Then, you add 5. 4. **Final calculation**: So, 7 + 5 equals 12. Therefore, the value of the expression 12 - (2 + 3) + 5 is indeed 12. This confirms that the correct answer aligns with the calculations made following the order of operations accurately.
