„Basic arithmetic operations for bases

zThe 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 operation

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.

Mode 3 - CPLX

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

Re

Real value

Im

Imaginary value

ab

Absolute value

ar

Argument value

 

 

 

Mode 4 - VLE

 

 

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.

zIn 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.

Mode 5 - QE

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

a x 2 + b x + c = 0, where x is unknown.

zIn 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.
