Negative and Complements

In binary, octal, and hexadecimal bases, the calculator represents
negative numbers using complement notation. The complement is
the result of subtracting that number from 10000000000 in that
number’s base by pressing [ +/– ] key in non-decimal bases.

Complex numbers calculation

Select the complex numbers mode by pressing [ CPLX ] key and

make sure “ CPLX ” indicator appears on the display. The calculator
enables you to add, subtract, multiply, and divide complex numbers.

Complex numbers are generally represented as a + b i, where a

is a real and b is imaginary.
