Casio fx-991es plus scientific calculator tips

About output:

By default, the data is displayed in the natural writing format, and the calculation result is displayed in the score format. For example, 0.5x0.5 is displayed as = 1/4. Although intuitive, it is slightly inconvenient to measure and estimate. Use

Shift --> mode (that is, setup ),

Select 1. Input and Output (Natural Writing type. Io is input output ),

Then, the display method of the calculation result is displayed.

Select 2. Lineo (linear output, O or output)

Then, it is easy and intuitive to use natural writing for input, and linear output for output.

(If I use the natural writing format I/O, I just want to use Lineo for output occasionally. I just need to add shift before the equals sign (=)

--------------------------

About variables:

0.35x0.44x1.36 --> shift --> RCL --> (-) [marked with a red on it ],

In this way, the result is put into register.

Registers such as B/C/D/E/F/M can be used in this way.
