VIIICHALK IN HAND, I START to make the grid on the chalk board:
Plus-plus, plus-minus, plus-everything, plus-nothing.
Ben said there was only eight, so it has to be how many word combinations there are, not what word comes first.
So: minus-minus, minus-everything, minus-nothing.
And: everything-everything, everything-nothing.
Then: nothing-nothing.
OK, that's ten. Ben could have been off.
What else did he say. "The problem is in the nothing-nothing grid..."
So I stared at it. Why was that a problem? How could double-nothing be a problem?
