» The Notch for Felling a Tree [HTML]

Description: In its September/October 1998 issue, Workbench, had an article on "Felling a Tree Safely." Part of the process of felling a tree is to cut a notch on the side of the tree toward the direction you want it to fall.

Description: Rounding Off: In a certain multi-million dollar company, Division Managers are required to submit monthly detail and summary expense reports on which the amounts are rounded, for ease of reading, to the closest $1,000. One month, a Division Manager's detail report shows $1,000 for printing and $1,000 for copying. In the summary report, the total for "printing and copying" is listed as $3,000. When questioned about it by the Vice President, he claims that the discrepancy is merely round-off error. In subsequent months, the Vice President notices that such round-off errors seem to happen often on this Division Manager's reports. Before the Vice President asks that the Division Manager re-create the reports without rounding, she wants to know how often this should happen.
