AAAaannndd the bot gets it wrong yet again!
2+3×16−2×21−3
2+48−42−3
50-42-3
8-3
5
You are correct, the answer is indeed 5. I apologize for the mistake in my previous response. Thank you for bringing it to my attention.
To find the value of the expression using the order of operations, we follow the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's calculate the expression step-by-step:
1. First, we perform any calculations inside parentheses. There are no parentheses in this expression.
2. Next, we evaluate any exponents. There are no exponents in this expression.
3. Then, we perform any multiplication and division from left to right. We start by calculating 3×16, which equals 48.
The expression now becomes: 2 + 48 − 2×21 − 3.
Next, we calculate 2×21, which equals 42.
The expression now becomes: 2 + 48 − 42 − 3.
4. Lastly, we perform addition and subtraction from left to right. We start by calculating 2 + 48, which equals 50.
The expression now becomes: 50 − 42 − 3.
We then calculate 50 − 42, which equals 8.
The expression now becomes: 8 − 3.
Finally, we calculate 8 − 3, which equals 5.
Based on these calculations, the value of the expression is 5.
Therefore, the correct answer is option A. 5.
