I need help understanding why we did not add certain things or subtract certain things to get to the cash balance. I understand points 1-3. Do not get points 4-11 & why some items aren't subtracted or added.

More specifically, can you explain why some items are classified as receivables and not cash?

Your answer is correct. The controller for Cullumber Co. is attempting to determine the amount of cash to be reported on its December 31, 2017, balance sheet.
