The fact that the panel doesn't call him on wrong answers makes me question him.

Still quite impressive--panel should have been told same thing as those at end.

That's pretty cool. He did get all the two-digit squares correct. A couple of the three digit calculations were a little off but still got some of the numbers right in the right order.

457 squared is 208,849. He was wrong and so was the panel.
