As a domain expert in the field of calculators and their functionalities, I can provide a comprehensive explanation of the "M+" function in calculators. The "M+" button is a feature found on many scientific calculators and is part of the memory function that allows users to store and recall numbers or results for later use.

In calculators, the "M+" function is used to add the current displayed number to the memory. This is particularly useful when you are performing a series of calculations and need to keep intermediate results for further use. For instance, if you are calculating the total cost of multiple items, you can use "M+" to store the cost of each item as you go along, and then recall these stored values later to find the total sum.

The process of using "M+" typically involves a few steps:
1. Perform a calculation.
2. Press "M+" to store the result in memory.
3. Continue with other calculations.
4. Use "MR" (Memory Recall) to recall the stored result when needed.

It's important to note that the memory in calculators is usually non-volatile, meaning that the stored values remain even after the calculator is turned off. This makes it a convenient tool for tasks that require the accumulation of results over time.

Additionally, calculators often have other memory-related functions such as "M-" for subtracting the displayed number from the memory, "MC" (Memory Clear) to clear the memory, and "MRC" (Memory Recall and Clear) which recalls the stored value and then clears the memory.

Now, let's move on to the translation of the above explanation into Chinese.
