Well
,
he
really
could
not
have
known
.
When
the
called
his
name
,
he
can
barely
believe
his
ears
,
and
looks
around
.
There
might
be
a
miracle
,
or
this
might
have
been
a
,
this
is
not
really
his
name
after
all
and
he
will
wake
up
from
this
nightmare
.
Then
he
picks
up
a
bunch
of
from
his
desk
.
He
is
walking
the
tiny
between
the
desks
,
and
he
thinks
"
aplusbtimesaminusb
equals
asquaredminusbsquared
"
.
Surely
this
is
what
the
teacher
will
ask
.
Surely
.
"
If
not
,
then
I
will
change
and
join
the
army
.
"
The
teacher
sits
down
and
puts
down
his
.
He
looks
at
the
bad
student
.
The
student
keeps
repeating
to
himself
,
"
aplusbtimes
?
"
and
takes
the
into
his
hand
.
The
teacher
looks
at
him
.
"
Have
you
prepared
for
your
lesson
?
"
he
asks
.
"
Yes
.
"
Of
course
,
he
has
.
Even
the
man
condemned
to
death
comes
prepared
:
he
takes
the
last
rites
and
has
his
hair
cut
short
.
"
Write
the
following
then
.
"
The
bad
student
faces
the
.
"
Bsquaredminusplusminussquarerootminusfouractimestwoa
.
"
And
the
bad
student
starts
writing
obediently
,
repeating
the
words
.
And
he
writes
,
and
he
writes
.
He
guesses
that
this
might
be
a
quadratic
equation
,
but
that
is
all
he
knows
.
He
writes
and
beautifully
.
He
one
line
here
and
shortens
another
line
there
;
he
walks
all
the
way
to
the
window
to
get
the
.
He
gains
time
.
May
be
the
will
be
over
soon
,
or
some
miracle
will
happen
.
He
will
not
spend
a
lot
of
time
here
,
by
the
teacher's
.
He
writes
"
a2
"
on
the
board
.
One
has
to
get
up
very
early
in
the
army
,
he
remembers
suddenly
.
But
it
is
worth
it
.
He
is
still
writing
very
slowly
.
An
ignorant
person
would
glance
at
this
scene
and
think
that
he
was
a
good
student
answering
.
But
an
expert
knows
what
it
means
when
someone
writes
the
two
with
such
great
care
.
There
is
deadly
silence
all
around
.
The
teacher
does
not
move
.
Now
the
student
must
say
something
.
"
The
quadratic
equation
.
.
.
.
"
he
starts
off
intelligently
and
he
closes
his
eyes
a
little
,
focusing
on
the
blackboard
.
"
The
quadratic
equation
.
.
.
.
"
he
as
if
he
was
trying
to
find
the
best
answer
from
the
many
answers
in
his
head
.
But
the
teacher
knows
what
this
means
.
"
Have
you
come
prepared
?
"
he
asks
dryly
.
"
Yes
,
Sir
.
"
He
says
this
very
quickly
,
but
he
seems
.
"
Let's
hear
it
then
,
"
says
the
teacher
.
And
the
bad
student
takes
a
deep
breath
.
And
he
starts
talking
.
He
expects
that
the
teacher
will
interrupt
him
at
the
second
sentence
,
but
he
does
not
say
a
word
.
The
bad
student
knows
that
what
he
is
saying
does
not
make
any
.
Still
the
teacher
does
not
say
anything
.
This
is
horrible
.
The
student's
voice
starts
shaking
.
He
sees
that
the
teacher
is
lifting
his
logbook
.
The
student
panics
and
starts
very
rapidly
.
"
The
quadratic
equation
derives
from
the
simple
equation
that
we
?
Sir
,
I
have
prepared
for
this
lesson
.
"
"
Ern
?
Polgár
,
"
says
the
teacher
loudly
.
What
is
going
on
?
Are
they
calling
another
student
already
?
Is
he
done
?
What
is
going
on
?
Is
he
dreaming
?
Ern
?
Polgár
comes
to
the
teacher's
desk
,
takes
a
piece
of
chalk
into
his
hand
and
stands
by
the
other
end
of
the
blackboard
.
"
The
quadratic
?
Sir
,
I
have
prepared
for
this
lesson
,
"
the
bad
student
is
still
talking
.
But
nobody
answers
.
And
now
he
is
standing
there
all
alone
,
alone
as
if
he
was
the
last
person
on
an
.
But
he
will
not
go
back
to
his
desk
.
The
teacher
did
not
send
him
back
to
his
desk
,
no
one
sent
him
back
.
He
is
still
answering
questions
.
Should
he
walk
back
to
his
place
?
No
,
he
prefers
to
there
,
stupidly
.
And
he
is
still
standing
there
,
still
standing
,
hoping
,
and
listening
to
the
other
student
.
Sometimes
he
,
showing
that
he
agrees
with
the
answer
and
that
he
knows
the
answer
.
He
will
not
give
up
.
After
a
while
he
becomes
weak
,
he
stops
talking
and
thinks
of
military
school
once
more
.
He
sees
infinity
,
a
big
,
blue
something
,
and
a
little
house
with
a
:
"
Entrance
to
the
fourth
infinity
"
.
There
are
hangers
in
the
house
where
the
parallel
lines
hang
their
hat
,
and
after
that
they
go
to
the
room
,
sit
behind
their
desk
and
welcome
each
other
.
The
parallel
lines
,
yes
.
.
.
.
They
are
in
the
class
of
infinity
,
understanding
,
goodness
and
philanthropy
where
he
shall
never
get
to
?
that
"
higher
grade
"
into
which
he
"
cannot
enter
because
of
his
insufficient
results
"
.
Ever
.
