Parentheses in simple Order of Operations: 4 Numbers

1. Follow the order of operations (PEMDAS/BODMAS).

2. First do the operation inside the parenthesis: $3 + 1 = 4$.

3. Then, perform the multiplication: $2 \times 4 = 8$.

4. Finally, perform the addition: $10 + 8 = 18$.

Let's start with the part inside the parentheses. 

$2+2=4$
Then we will solve the exercise from left to right 

$8:2=4$
$4 × (4)=16$

The answer: $16$

To solve the expression $15 + 3 \times (6 - 2)$, follow the order of operations (PEMDAS/BODMAS):

1. **Parentheses**: Solve inside the parentheses first.

$6 - 2 = 4$

2. **Multiplication**: Next, perform the multiplication.

$3 \times 4 = 12$

3. **Addition**: Finally, perform the addition.

$15 + 12 = 27$

Thus, the correct answer is $27$.
