You unwrap a giant Hershey bar. The type that is scored, so that it can be broken into smaller pieces. You note the bar has exactly m squares along its length and n squares along its width.

You wish to break the bar up into all small squares. How many breaks are required? Stacking is not allowed, and the breaks are always made along a straight line.

Stacking is not allowed, and the breaks are always made along a straight line.


Only stacking in a third dimension is not allowed? Cut pieces may be moved around on the plane or rotated to be cut further?

What about flipping of pieces? (although I fail to see how that may be advantageous at this point)
