Well, not captions, but a synopsis.
Guy answers math questions in a ridiculous amount of time. He gets a number from the audience, such as 547, and performs the calculation in his head in fraction of a second.
Then he squares a 4 digit number in his head. 9,758.
Then says how he can square a 5 digit number, but most standard calculators can't.
Then takes 8649, and has the audience members multiply it by any 3-digit number they want to. It will most likely yield a 7-digit number. They then call out any six digits from that answer, in any order they want.
The guy will then
try to determine the digit that they left out, and he of course gets them all correct.
Then a lame joke around 7:55: "For my next number..."
He asks the audience to raise their hands if they know the day of the week that they were born on. He then asks them to tell him only the date and the year. He is able to determine the day of the week, correctly. So he can do that fun calendar trick thing.
At 11:00, he tries to square a 5-digit number, but does it while thinking through it out loud. 57,683. Break it down into three parts:
57,000^2 + 683^2 + 57,000*683*2
At 12:32: "Now let me recap." And he proceeds to put the cap back on the marker. Har har.
He apparently has some pneumonic device that he uses to store numbers in his mind, and then does a little Rainman impression.
At about 14:00, he starts rambling insanely fast with numbers, and something about "cookie fishin." Mixes in words and numbers then in some weird manner. "466, add that to fishin, to get, um, 328,489."
:Q And somehow, that all makes sense in his mind. And the crowd goes wild....
