AAAaannndd the bot gets it wrong yet again!
12÷2×3−(7−5)
12÷2×3−2
6×3−2
18-2
16
I apologize for the mistake in my earlier response. You are correct, the answer is 16. Thank you for bringing it to my attention.
To find the value of the expression using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right), follow these steps:
Step 1: Evaluate expressions within parentheses, if any. In this expression, there is (7-5) inside parentheses.
(7-5) = 2
The expression now becomes:
12÷2×3 - 2
Step 2: Perform any multiplication or division from left to right. Here, we have division and multiplication.
12 ÷ 2 = 6
Now, the expression becomes:
6 × 3 - 2
Step 3: Perform remaining addition or subtraction from left to right. Here, we have subtraction.
6 × 3 = 18
Now, the expression becomes:
18 - 2
Step 4: Perform the subtraction.
18 - 2 = 16
So, the value of the expression is 16.
Therefore, the correct answer is C. 16.
B. 6
Following the order of operations, first we do the division: 12 ÷ 2 = 6
Then we multiply by 3: 6 × 3 = 18
Next we do the subtraction inside the parentheses: 7 - 5 = 2
Finally, we perform the subtraction outside the parentheses: 18 - 2 = 16
Therefore, the answer is 6.
