z

 

The unit enables you to calculate in number base other than 
decimal. The calculator can add, subtract, multiply, and divide 
binary, octal, and hexadecimal numbers.    See Example 61. 

„ 

Logical operations are performed through logical products (AND), 
negative logical (NAND), logical sums (OR), exclusive logical sums 
(XOR), negation (NOT), and negation of exclusive logical sums 
(XNOR).  See Example 62. 

z

 

Complex mode enables you to add, subtract, multiply, and divide 
complex numbers. See Example 63. The results of a complex 
operation are displayed as follow : 

 Real 

value 

 Imaginary 

value 

 Absolute 

value 

 Argument 

value 

Variable linear equations (VLE) mode can solve a set of 
simultaneous equations with two unknowns as follows : 

a x + b y = c 
d x + e y = f, where x and y are unknown. 

z

 

In VLE mode, you just enter each coefficient ( a, b, c, d, e, f ) in 
the correct order, and the calculator automatically solves for x, y.  
See Example 64. 

Quadratic equations (QE) mode can solve a equations as follows : 

a x 

2

 + b x + c = 0, where x is unknown. 

z

 

In QE mode, you just enter each coefficient ( a, b, c ) in the correct 
order, and the calculator automatically solves for all x values.  
See Example 65.
