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 prac-
tice."
"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 seven-
teen 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 fwenty-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 horn-swoggling."
"Oh no, sir," said Aub in a sweat. "It only seems compli-
cated 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 Gl model)
and struck it at random. Make a five seven three eight on
