Key Functions

1. Extra Large Display:
   This refers to the screen of the calculator. An extra-large display helps users to easily see and read the numbers, especially useful for lengthy calculations or in environments where a quick glance is needed.

2. Decimal Digits Setting:
   This function allows users to set the number of decimal places they want their calculations to be rounded to. It ensures accuracy and precision in calculations that involve fractions or decimals.

3. Back Space:
   The backspace key lets users delete the last entered digit or character. This is useful if a mistake is made during input and can save time compared to clearing the entire entry.

4. All Clear (AC):
   The “AC” button will clear everything on the display. This includes any numbers you’ve entered or results that are currently shown, resetting the calculator to its initial state.

5. Solar Panel:
   The solar panel powers the calculator using light, which can be from the sun or ambient room light. This makes the calculator energy efficient and reduces the need for battery replacements.

6. OFF Button:
   This button is used to manually turn off the calculator. While many calculators automatically turn off after a period of inactivity, the OFF button provides a manual option.

7. Memory Load/Clear (MR):
   The “Memory Recall” or “Memory Read” button allows users to recall a number they’ve stored in the calculator’s memory. It’s useful for multi-step calculations where a particular number will be used multiple times. If pressed after storing a value, it will display that stored value. Additionally, it can often be used to clear the memory when combined with other keys.

8. Memory Plus/Minus (M+/M-):
   These buttons allow users to add or subtract the currently displayed number to or from a stored number in memory. For instance, after performing a calculation, you can use the M+ key to add this result to a previously stored value in memory, or the M- key to subtract it.

Overall, these features enhance the versatility and usability of the calculator, making it a useful tool for a variety of mathematical tasks.
