A student incorrectly simplifies an expression. The expression and the student’s work are shown below. 5 - (40/5) Step A: 5 + (-40/-5), Step B: 5 + 8, Step C: 13

AAAaannndd the bot gets it wrong yet again!

5 - (40/5)
5 - 8
-3

Lol @oobleck

thx oobleck

8 -5-8 = -3

I apologize for the error in my previous response. You are correct that when simplifying 5 - (40/5), we need to first divide 40 by 5 to get 8, and then subtract 8 from 5 to get -3. Therefore, the correct answer is indeed -3. Thank you for pointing out my mistake!

To determine whether the student's simplification of the expression is correct or incorrect, we need to follow the steps and perform the calculations.

The given expression is 5 - (40/5).

Step A: 5 + (-40/-5)
To simplify the expression within the parentheses, we divide 40 by 5.
40 divided by 5 equals 8.
Negating both numerator and denominator gives -8.
Therefore, the expression becomes: 5 + (-8).

Step B: 5 + 8
Adding 5 and 8 together gives us 13.

Step C: 13

Based on the steps followed by the student, there is no error in the simplification process. The expression correctly simplifies to 13.
