General Weider said, "I find this atmosphere of mystery childish."
"You won't in a moment," said Shuman. "This is not something we can leak to the firstcomer. - Aub!" There was something imperative about his manner of biting off that one-syllable name, but then he was a great Programmer speaking to a mere Technician. "Aub! How much is nine times seven?"
Aub hesitated a moment. His pale eyes glimmered with a feeble anxiety. "Sixty-three," he said.
Congressman Brant lifted his eyebrows. "Is that right?"
"Check it for yourself, Congressman."
The congressman took out his pocket computer, nudged the milled edges twice, looked at its face as it lay there in the palm of his hand, and put it back. He said, "Is this the gift you brought us here to demonstrate? An illusionist?"
"More than that, sir. Aub has memorized a few operations and with them he computes on paper."
"A paper computer?" said the general. He looked pained.
"No, sir," said Shuman patiently. "Not a paper computer. Simply a sheet of paper. General, would you be so kind as to suggest a number?"
"Seventeen," said the general.
"And you, Congressman?"
"Twenty-three."
"Good! Aub, multiply those numbers and please show the gentlemen your manner of doing it."
"Yes, Programmer," said Aub, ducking his head. He fished a small pad out of one shirt pocket and an artist's hairline stylus out of the other. His forehead corrugated as he made painstaking marks on the paper.
General Weider interrupted him sharply. "Let's see that."
Aub passed him the paper, and Weider said, "Well, it looks like the figure seventeen."
Congressman Brant nodded and said, "So it does, but I suppose anyone can copy figures off a computer. I think I could make a passable seventeen myself, even without practice."
"If you will let Aub continue, gentlemen," said Shuman without heat.
Aub continued, his hand trembling a little. Finally he said in a low voice, "The answer is three hundred and ninety-one."
Congressman Brant took out his computer a second time and flicked it, "By Godfrey, so it is. How did he guess?"
"No guess, Congressman," said Shuman. "He computed that result. He did it on this sheet of paper."
"Humbug," said the general impatiently. "A computer is one thing and marks on paper are another."
"Explain, Aub," said Shuman.
"Yes, Programmer. - Well, gentlemen, I write down seventeen and just underneath it, I write twenty-three. Next, I say to myself: seven times three - "
The congressman interrupted smoothly, "Now, Aub, the problem is seventeen times twenty-three."
"Yes, I know," said the little Technician earnestly, "but I start by saying seven times three because that's the way it works. Now seven times three is twenty-one."
"And how do you know that?" asked the congressman.
"I just remember it. It's always twenty-one on the computer. I've checked it any number of times."
"That doesn't mean it always will be, though, does it?" said the congressman.
"Maybe not," stammered Aub. "I'm not a mathematician. But I always get the right answers, you see."
"Go on."
"Seven times three is twenty-one, so I write down twenty-one. Then one times three is three, so I write down a three under the two of twenty-one."
"Why under the two?" asked Congressman Brant at once.
"Because - " Aub looked helplessly at his superior for support. "It's difficult to explain."
Shuman said, "If you will accept his work for the moment, we can leave the details for the mathematicians."
Brant subsided.
Aub said, "Three plus two makes five, you see, so the twenty-one becomes a fifty-one. Now you let that go for a while and start fresh. You multiply seven and two, that's fourteen, and one and two, that's two. Put them down like this and it adds up to thirty-four. Now if you put the thirty-four under the fifty-one this way and add them, you get three hundred and ninety-one and that's the answer."
There was an instant's silence and then General Weider said, "I don't believe it. He goes through this rigmarole and makes up numbers and multiplies and adds them this way and that, but I don't believe it. It's too complicated to be anything but homswoggling."
"Oh no, sir," said Aub in a sweat. "It only seems complicated because you're not used to it. Actually, the rules are quite simple and will work for any numbers."
"Any numbers, eh?" said the general. "Come then." He took out his own computer (a severely styled GI model) and struck it at random. "Make a five seven three eight on the paper. That's five thousand seven hundred and thirty-eight."
"Yes, sir," said Aub, taking a new sheet of paper.
"Now," (more punching of his computer), "seven two three nine. Seven thousand two hundred and thirty-nine."
"Yes, sir."
"And now multiply those two."
"It will take some time," quavered Aub.
"Take the time," said the general.
"Go ahead, Aub," said Shuman crisply.
Aub set to work, bending low. He took another sheet of paper and another. The general took out his watch finally and stared at it. "Are you through with your magic-making, Technician?"
"I'm almost done, sir. - Here it is, sir. Forty-one million, five hundred and thirty-seven thousand, three hundred and eighty-two." He showed the scrawled figures of the result.
