In this post we demonstrate how to write alphabets on the Fx-991ES PLUS and Fx-570MS calculator by Casio. Both calculators are very similar, except one is able to write more letters than the other. We will see this in more detail.
Write alphabets on Casio Calculator – Basic Technique
The general idea is to find which key, in combination with the ‘SHIFT’ or ‘ALPHA’ keys will produce the desired letter. If we look at the keypads of both calculators, we can see some characters written about the keys in either pink or yellow.
Put simply, those letters in pink will appear if the corresponding key is used with the alpha button. Similarly letters written in yellow appear when used with the shift key.
You do not need to hold the alpha or shift keys down will pressing the other button. Just a simple tap to active the shift or alpha mode is enough. At the top left of the screen you would see a [A] or [S] icon illuminate to indicate if you are in Alpha or Shift mode.
Lets look at a few examples and list out the required key combinations to write each letter of the alphabet on a Casio Calculator.
