Its keyboard layout is identical to that of the 8-digit CASIO fx-82LB, the CASIO fx-82SX and probably others as well.
It is the sibling of the CASIO fx-500 which has a different case (and different batteries) but shares the same manual. The CASIO fx-95 uses cheaper and long lasting AA batteries. The CASIO fx-500 has a sleeker thin case though.
It has all the standard scientific and statistical functions but has extra functionality as well: it can solve quadratic functions and sets of simultaneous linear functions with either two or three unknowns. Since it doesn’t have a dot matrix display it takes a little exercise getting used to how to use these functions.
Take for instance the quadratic equation solver for solving the formula:
ax2 + bx + c = 0
Use
MODE
1
to select the solver. At the left of
the display a little indicator displays
a.
Type the value for a and press
M+
and do the same for inputs b and c.
The solver for simultaneous linear functions works in a similar manner but one has to enter the values for multiple equations. The current equation number is indicated by a single digit at the left of the display.
To change the batteries one first has to unscrew four screws at the back.
This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the EXP key will enable you to enter the exponent, otherwise it will enter the constant π.
