4 - 2 Negative expressions
• 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 press-
ing [ NEG ] key in non-decimal bases.
See Example 41.
4 - 3 Basic arithmetic operations for bases
• The unit enables you to calculate in number base other than decimal. The
calculator can add, subtract, multiply, and divide binary, octal, and hexa-
decimal numbers. See Example 42.
4 - 4 Logical operation
• Logical operations are performed through logical products (AND), nega-
tive logical (NAND), logical sums (OR), exclusive logical sums (XOR),
negation (NOT), and negation of exclusive logical sums (XNOR).
See
Example 43.
5 Mode 3 - CPLX
• Complex mode enables you to add, subtract, multiply, and divide complex
numbers.
See Example 44. The results of a complex operation are dis-
played as follow :
Re Real value Im Imaginary value
ab Absolute value ar Argument value
6 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.
• 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 45.
7 Mode 5 - QE
Quadratic equations (QE) mode can solve a equations as follows :
a x
2
+ b x + c = 0, where x is unknown.
• 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 46.
