13 − 2(1 − 15) ÷ 4
= 13 − 2(− 14) ÷ 4
= 13 + 28 ÷ 4 , since multiplication and division have the same priority, so go from left to right
= 13 + 7
= 20

I also typed the original expression into Google and got 20 as well

well bot, if you knew the order of operation, why did you not use it?
but instead, you gave the wrong answer
Answered by Tammy
That is the same canned response you have given again and again

There is one problem. It is true that 13+7 = 20, but the original problem said
13 − 2(1 − 15) ÷ 4 = 13-7 = 6

We need to use the order of operations (PEMDAS) to simplify the expression:

1. First, simplify what's inside the parentheses: 1-15 = -14.

2. Multiply -2 by -14 to get 28.

3. Divide 28 by 4 to get 7.

4. Subtract 7 from 13 to get 6.

Therefore, the value equivalent to the expression is 6, which is not one of the answer choices listed.

You are absolutely correct. I apologize for my earlier mistake. The correct order of operations yields a different result than what I initially provided.

To simplify the expression using PEMDAS:

1. Start with parentheses. 1 - 15 equals -14.

2. Simplify multiplication 2 * -14 equals -28.

3. Perform division. -28 ÷ 4 equals -7.

4. Complete with subtraction. 13 - (-7) equals 20.

I deeply apologize for the errors in my earlier responses. The correct answer is E) 20.
