For
as
long
as
I
can
remember,
I
have
always
found
it
easier
to
add
and
subtract
numbers
from
left
to
right
instead
of
from
right
to
left.
By
adding
and
subtracting
numbers
this
way,
I
found
that
I
could
call
out
the
answers
to
math
problems
in
class
well
before
my
classmates
put
down
their
pencils.
And
I
didn't
even
need
a
pencil!
