I have a casio fx-115ES and i have some problems that require variables.. example.. 2x3(cubed)-686.
how do i enter this into my calculator to solve?
Hello,
When you press the key between X^2 and log it gives you a template where you enter the base of the power (bigger rectangle) and the exponent (the smaller raised rectangle) . Using the 3 cubed exemple is not good because base and exponent are the same.
Exemple :15 cubed.
Press the key with an X with a small raised rectangle. The cursor blinks at the left side of the raised rectangle. Enter the exponent (3). Then use the left arrow to move the cursor to the base. Enter 15 and press [=]. The result is displayed as 3375 or in some other equivalent form (with a power of ten.)
Hope it helps.

With variables:
In what follows physical keys are represented inside square brackets [ ] while the SHIFTed or ALPHA keys are inside parentheses. Exemple [ ) ] is a left parenthesis and [ALPHA][ ) ] displays X; [X^2] calculates the square of a number, while [SHIFT][X^2] calculates the cube.
2[ * ][APLHA] [)] (X) [SHIFT][X^2] (X^3) -686
OOPs [ ) ] is a right parenthesis.
