When
there are two or
more
operators at the same priority
level,
the
expression
will be
evaluated
from
left to
right.
(The
exponentiation
will be evaluated
from
right
to
l
e ft.)
Note
that
with
A+B-C,
for example, the answer is the same whether the
additi
o n
or
the
subtraction
is
done
first.
When an expression
contains
multipl
e nested
parentheses,
the
innermost
set
is
evaluated
first
and
evaluation
then
proceeds
outward.

Operators on BASIC mode cf the
SHARP COMPUTER
are evaluated with the
following
priorities from
highest
to
lowest:
OperatorPrtority
Since
the
COMPUTER
must
have
some way
to
decide
between
these options,
it
uses
its rules of operator
priority.
Because
division
has a
higher "priority"
than
addition
(see below), it
will
choose to do the division first and
then
the
addition,
i.e., i
t will
choose the second option and
return a
value
of
65
for
the
expression.
or
5
+
45
100
+

=

as
either a
calculation
or
as
a part
of
a
program,
the COMPUTER
does
not
know
whether
you
meant:
100
/
5+45
When the
SHARP COMPUTER
is
given
a
complex
expression,
it evaluates
the
parts
of the
expression
in
a
sequence determined
by the
priority of the
individual
parts of
the
expression.
