How do you use the MRC button on a calculator?

Ah, the MRC button on a calculator is a handy little tool. It stands for Memory Recall, which means it brings back whatever number you stored in the calculator's memory. Simply press the MRC button after you've stored a number, and it will display that number for you to use in your calculations. Just like adding a happy little tree to your painting, the MRC button can add a touch of simplicity and convenience to your math equations.
