Data Input Precautions
• S S inputs the same data twice.
•You can also input multiple entries of the same data us-
ing
A G. To input the data “20 and 30” five times, for
example, press 20
P 30 A G 5 S.
• The above results can be obtained in any order, and not
necessarily that shown above.
•To delete data you have just input, press
A U.
Complex Number Calculations
(CMPLX Mode)
•Press F 2 to enter the CMPLX Mode for calculations
that include complex numbers.
•You can use variables A, B, C and M only. Variables D,
E, F, X, and Y are used for storage of the imaginary parts
of values and so cannot be used by you.
