calculation. SRP-285 can use up to 22 consecutive levels of
parentheses in a single calculation. See Example 14.
z
Closed parentheses occurring immediately before operation of the
[ ENTER ] key may be omitted, no matter how many are required.
See Example 15.
z
A multiplication sign " x " occurring immediately before an open
parenthesis can omitted. See Example 16.
(Note) : The calculator can auto-correct abbreviated
multiplication in front of all functions, except memory
variables, left parenthesis, type B functions.
z
Henceforth, abbreviated type will not be used in this manual.
See Example 17.
z
The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ]
[ EXP ] 2. Be sure to enter [ x ] 1 between the [ ) ] and [ EXP ] in the
below example. See Example 18.
2–4 Percentage
Calculation
z
[ 2nd ] [ % ] divides the number in the display by 100. You can use
this key sequence to calculate percentages, add-ons, discounts,
and percentages ratios. See Example 19.
2–5
Continuous calculation function
z
The calculator enables you to repeat the last operation executed
by pressing [ = ] key for further calculation. See Example 20.
z
Even if calculations are concluded with the [ = ] key, the result
obtained can be used for further calculation. See Example 21.
2–6 Answer
Function
z
Answer function stores the most recently calculated result. It is
retained even after the power is turned off. Once a numeric value
or numeric expression is entered and [ ENTER ] is pressed, the
result is stored by this function. See Example 22.
(Note) : Even if execution of a calculation results in an error,
however, Answer memory retains its current value.
2–7 Logarithm
And
Antilogarithm
z
The calculator can calculate common and natural logarithms and
anti-logarithms using [ LOG ], [ LN ], [ 2nd ] [ 10
x
], and [ 2nd ]
[ e
x
]. See Example 23.
2–8 Fraction
Calculation
Fraction value display is as follow :
