    To calculate 15 
10 
 ×  3 
10 
 in the decimal mode, and then convert 
the result to hexadecimal, binary, and octal
     Ax(DEC) 15 * 3 = 
45  
      M(HEX) 2d  
      l(BIN) 101101 
     i(OCT) 55  
    Note:  • You may not be able to convert a value from a number 
system whose calculation range is greater than the calculation range 
of the resulting number system. • The message “Math ERROR” 
indicates that the result has too many digits (overflow).
  Logical and Negation Operations
  Your calculator provides you with logical operators (And, Or, Xor, Xnor) 
and functions (Not, Neg) for logical and negation operations on binary 
values. Use the menu that appears when you press X(LOGIC) to 
input these logical operators and functions. 
  All of the following examples are performed in the binary mode 
( l(BIN)).
  To determine the logical AND of 1010 
2 
 and 1100 
2 
 (1010 
2 
 and 
1100 
2 
)
     A 1010 X(LOGIC) 1(And) 1100 = 
1000  
   To negate (take the two’s complement) of 101101 
2 
(Neg(101101 
2 
))
AX(LOGIC) X(LOGIC) 3(Neg) 101101 = 
1111010011  
    Note:  In the case of a negative binary, octal or hexadecimal value, the 
calculator converts the value to binary, takes the two’s complement, 
and then converts back to the original number base. For decimal 
(base-10) values, the calculator merely adds a minus sign.
  Equation Calculations (EQN) 
  The EQN Mode lets you solve equations up to three degrees and 
simultaneous linear equations with up to three unknowns.
  1. Press  NNN1(EQN) to enter the EQN Mode. 
  2. On the menu that appears, select an equation type.
