Memory Plus (M+)

The Memory Plus (M+) function allows users to add a number to the current value stored in memory. To use this function, the user enters the desired number and then presses the M+ button. The calculator then adds the number to the current value in memory. This function is useful when the user needs to accumulate several values for later use.

Memory Minus (M-)

The Memory Minus (M-) function allows users to subtract a number from the current value stored in memory. To use this function, the user enters the desired number and then presses the M- button. The calculator then subtracts the number from the current value in memory. This function is useful when the user needs to subtract several values from a running total.

Memory Recall (MR)

The Memory Recall (MR) function allows users to retrieve the value stored in memory. To use this function, the user simply presses the MR button. The calculator then displays the value stored in memory. This function is useful when the user needs to recall a previously stored value for use in a calculation.

Overall, memory functions are an essential feature of modern calculators. They allow users to save time and effort by storing and recalling numbers without having to re-enter them manually. By using memory functions, users can perform complex calculations more efficiently and accurately.
