simplify 8/2 + 9 (12 divided by 3x2)-7 explain each of your steps i thought it was 1
rewriting this:
8/2 + 9 (12 ÷ 3(2) ) - 7
= 4 + 9(4)(2) - 7
= 4 + 72 - 7
= 69
according to the order of operation rules, multiplication and division is performed in the order they come from left to right

To simplify the expression 8/2 + 9 (12 ÷ 3x2) - 7, we need to follow the order of operations (also known as PEMDAS).
Step 1: Simplify within parentheses
Inside the parentheses, we have 12 ÷ 3x2. According to the order of operations, we need to do the multiplication first, and then the division.
12 ÷ 3 equals 4, and then 4 multiplied by 2 equals 8. So, the expression becomes:
8/2 + 9 (8) - 7
Step 2: Perform any multiplications or divisions from left to right
Next, let's divide 8 by 2:
8 ÷ 2 equals 4. Updating the expression:
4 + 9 (8) - 7
Step 3: Perform any multiplications
Now, let's multiply 9 by 8:
9 multiplied by 8 equals 72. Updating the expression:
4 + 72 - 7
Step 4: Perform any additions or subtractions from left to right
Finally, let's evaluate the addition and subtraction:
4 + 72 equals 76, and then 76 - 7 equals 69.
Therefore, the simplified expression is 69.
To simplify the expression 8/2 + 9 (12 ÷ 3 × 2) - 7, follow the order of operations (also known as PEMDAS) to determine the correct steps to take:
Step 1: Deal with parentheses
In the expression, we have (12 ÷ 3 × 2) inside parentheses. Start by simplifying this portion:
12 ÷ 3 = 4
4 × 2 = 8
After simplifying the expression in the parentheses, the original expression becomes:
8/2 + 9 (8) - 7
Step 2: Perform multiplications and divisions from left to right
Now, let's address the multiplication operation of 9 times 8:
9 × 8 = 72
After performing this operation, the expression simplifies further:
8/2 + 72 - 7
Step 3: Solve remaining addition and subtraction from left to right
Finally, calculate 8 divided by 2:
8 ÷ 2 = 4
Now, we can simplify the expression completely:
4 + 72 - 7
Step 4: Perform remaining addition and subtraction
Calculate the addition:
4 + 72 = 76
Now, the expression becomes:
76 - 7
Calculate the subtraction:
76 - 7 = 69
Therefore, the simplified expression is 69.
So, the answer to the question is not 1, but it is 69.
