What is the result of 9 + 3(2² - 4)?

To solve the expression (9 + 3(2² - 4)), we need to follow the order of operations, often abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Begin by evaluating the expression inside the parentheses: (2² - 4).

• First, calculate (2²) which equals (4).

• Next, subtract (4) from that result: (4 - 4 = 0).

2. Now substitute back into the expression, which simplifies to (9 + 3(0)).

3. Next, calculate (3(0)):

• This results in (0).

4. Finally, add this result to (9):

• (9 + 0 = 9).

Thus, the result of the expression (9 + 3(2² - 4)) is (9), confirming that the answer is indeed the correct one.
