CHAPTER 3
• If an answer is smaller than 1 (0.XXX...), the zero (0) indication in the first digit left of
the decimal point is omitted on the display.
• All calculations inside parentheses ( ) are completed first.
In example 3 above, if the parentheses were omitted, the calculation result would be
the same as that of example 2.
• A negative number is entered by pressing
—
(not
-
) before the number, as
shown in example 5.
If
-
is mistakenly used in place of
—
, an error will be generated. (Example:
For the expression “5 × (-3)”, the use of
-
for the “-” sign of “-3” generates an
error. Use
—
.)
• The EXP key (secondary function of
,
) is used to input exponents.
• In example 7, the input of
j
before
(
may be omitted.
• A maximum of 32 parentheses (including those of other calculation instructions) can
be used. However, the numeric values stored in an expression must not exceed 14.
