Parentheses Order of Operations Practice Problems

To solve the equation, follow these steps:

1. Start by solving the expression inside the parentheses: $12 + 8$.

2. Calculate $12 + 8$ to get $20$.

3. Now divide the result by 4: $20 \div 4$.

4. Calculate $20 \div 4$ to get $5$.

Therefore, the final answer is $5$.

First, solve the expression inside the parentheses:
$8 + 5 = 13$

Then subtract from 25:
$25 - 13 = 12$

First, solve the expression inside the parentheses:
$10 + 7 = 17$

Then subtract from 30:
$30 - 17 = 13$

To solve the equation, follow these steps:

1. Start with the expression inside the parentheses: $50 - 10$.

2. Calculate $50 - 10$ to get $40$.

3. Now multiply the result by 2: $40 \times 2$.

4. Calculate $40 \times 2$ to get $80$.

Therefore, the final answer is $80$.

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

We will therefore start by simplifying the expression inside the parentheses and calculate the result of the addition within them, then - we will first perform the division operation:

$(85+5):10= \\ 90:10= \\ 9$

$$Therefore, the correct answer is answer A.
