Specific Buttons On This Calculator

1. GT (Grand Total) Button

This button is used to add up all the results (totals) that you have done on the calculator. For example, if you have done several separate calculations and want to see the sum of them all at once, pressing the GT button will show the grand total of all the calculations.

2. M+ (Memory Plus) Button

This button is used to add any number to the memory.
Usage: If you type “50” and then press M+, this number will be stored in the calculator’s memory. If you later type “30” and press M+ again, “80” will now be stored in the memory (50+30=80).

3. M- (Memory Minus) Button

This button is used to subtract any new number from the number in memory.
Usage: If “80” is already in memory and you type “20” and press M-, “60” will remain in memory (80-20=60).

4. MRC (Memory Recall & Clear) Button

This button has two functions:

Pressing it the first time displays the number stored in memory (Recall).

Pressing it again clears the memory (Clear).

5. +/- (Plus Minus) Button

This button is used to change the sign of any number.
Usage: If you have written “25” and press +/-, it will change to “-25”, and pressing it again will change to “+25”.

6. MU (Mark-Up) Button

This button is mostly used in business to calculate profit margin.
Usage: If an item is priced at Rs. 500 and you want to sell it with a 20% profit, then do this:

1. Write 500

2. Press MU

3. Type 20 and press %

4. The calculator will automatically show the price at which you have to sell the item.

✔ The MU button is very useful for shopkeepers and businessmen.
✔ M+, M-, and MRC are useful for those who want to save large calculations in memory and use them later.
✔ GT is useful for those who want to find the grand total of various calculations.

These buttons make the calculator more powerful and useful, especially useful for business people.
