A multiplication sign " x " occurring immediately before an open 
parenthesis can omitted.    See Example 17. 

(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 18. 

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 19.

Percentage Calculation

z

[ 2nd ] [ % ] divides the number in the display by 100. You can use 
this key sequence to calculate percentages, add-ons, discounts,

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 [ 

 ] is pressed, the 

result is stored by this function.    See Example 24. 

(Note) :  Even if execution of a calculation results in an error, 

however, Answer memory retains its current value.

z

The calculator can calculate common and natural logarithms and 
anti-logarithms using [ log ], [ ln ], [ 2nd ] [ 10 

x

 ], and [ 2nd ]   

[ e 

x

 ].    See Example 25~27.
