Casio FX 82Sx Instructions
Performing calculations in the classroom, in the office, or at home using Casio FX 82Sx can be a cinch once you know which buttons perform certain operations. The FX performs up to 9,000 hours of operation, features multiple scientific functions and allows an output of up to 10 digits on the display. Learn how to remove the back of the calculator for battery installation, access different mode functions, what each mode function does, enter a basic problem, how to get an answer to a basic problem and how to enter a number into the calculator as a constant.

Insert batteries into the calculator by first turning the calculator onto its face. With a small Philips-head screwdriver, unscrew the six screws securing the back to the calculator, and remove the calculator back. Install two new AA batteries into the chamber, following polar indicators. Replace the back cover, making sure the screws are tight.

Enter mode commands to perform specific operations. Push the "Mode" and "." Key simultaneously to perform "SD" calculations (standard deviation), press "Mode" and "0" to perform "COMP" calculations (normal calculations), press "Mode" and "4" to perform "DEG" calculations (operations using degrees), press "Mode" and "5" to perform "RAD" calculations (using radians), press "Mode" and "6" to perform "GRA" operations (calculations with grads), press "Mode and "7" to perform "FIX" calculations (decimal place specification), press "Mode" and "8" to peform "SCI" calculations (significant digit specification), and press "Mode" and "9" to perform the "NORM" operation (cancels "FIX" and "SCI" settings.

Enter a basic problem into the calculator like you would write it down on paper. Use the "COMP" mode to perform basic calculations. To create a single basic problem, there should be at two numbers and a function. Enter a number and a symbol and then a number like this: "23 + 11." Push the "=" button to get your answer, which should look like this: "23 + 11 = 34."

Enter a plus, multiplication, minus, or division sign twice after an number to make that number a constant in a basic problem. You'll know the number has been entered as a constant, because a "K" will be displayed next to the number. For instance, entering "4.3 + +" and then a "3" will make the answer "7.3". Follow this operation up by entering the number "8" and then pushing the equals sign again will render a new answer of "12.3." The number 3 and then number 8 were added to the constant number 4.3 to produce two different answers.
