Data Input Precautions

•SS 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 2to 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.
