W3 quiz Q9 on trans conv


I argue X=-2 (1*(-1)+21+3(-1)) instead of 2 in the answer. Please consider modifying this, if you agree. Thanks.

Hi Retainer,

Thanks for your question. After reviewing the operation again, I do obtain the same result as the quiz, following the same transformations as in the video of the lecture. I share with you the intermediate results of the cell X in all the four transformations.
Transformation of input 1: X = -1
Transformation of input 2: X = -1 + 2 = 1
Transformation of input 3: X = 1 -3= -2
Transformation of input 4: X = -2 + 4 = 2

Hope to have helped you understanding the solution.

Best,

Rosa
