## How does the memory function of the calculator work?

Our calculator has four memory keys with the letters M for 'Memory'. If, for example, you have to add the value of 9.743 to different numbers again and again, you will appreciate the memory function. Enter the number 9.743 and press the 'MS' key. The number is now stored in the temporary memory. If you now want to calculate 10 + 9.743, for example, type 10 + MR and you will get the result, which is 19.743. The 'MR' key here stands for 'Memory Recall', i.e. reading out the memory.

If you want to add a value to the value in the memory, enter this value and then use the 'M+' key. The current value is added to the value in the memory. The 'M-' key works in the same way by subtracting the value from the memory.

The numbers remain in the memory as long as the calculator is active. If you want to clear the memory, simply use the 'MC' key. The meaning should be self-explanatory with 'Memory Clear'.

- MS = Memory Store = Stores the current value in the memory
- MR = Memory Recall = Retrieves the stored value and inserts it into the current calculation
- M+ = Memory Add = Adds the current value to the memory
- M− = Memory Sub = Subtracts the current value from the memory
- MC = Memory Clear = Clears the memory
