The Casio Scientific Calculator is a convenient and versatile student calculator. It has many functions but the method is not complicated. Here is how to use the function keys of the Casio N78 calculator.

First take off the lid of the calculator, then turn it on. At this time, you will see that most of the keys on the calculator panel have symbols, letters and other yellow fonts. These fonts are the second function of each corresponding button of the calculator.

When we need to use these second function keys, we need to use the SHIFT function key on the calculator panel.

After pressing the SHIFT function key, the following display will appear on the display. When there is “s” on the display, it is in the state of the button function 2. If there is no “s”, it is in the function one state.
