Calculator and pen doing what they do best.

For people like me who cannot add numbers that have more than three digits, calculators have been a lifeline. No, please do not ask how I passed my math exams. That is something I do not wish to recall.

A calculator was my best friend growing up but then I realized that I still didn't know just what all those buttons were for. Yes, yes, shame on me.

Besides the square-root button, which is the single-most helpful button in the world, the rest was Greek to me. So, for fellow clueless souls, here it is. You can thank me later.

This is a standard calculator.

This is what the buttons do:

AC: All clear. It will remove all the previous equations and take you to 0.

CE: Clear Entry. It is the backspace of a calculator. Pressing this button will remove the last digit.

+/-: This button will change the number on screen to positive or negative.

MS: Memory Store. It puts the number on screen to save. Press this button if you need to use a number over and over.

MRC: Memory Recall. It uses the number that has been saved in memory.

M+/M-: Memory Add/ Memory Subtract. It takes the displayed number and adds or subtracts it from the memory and saves the result back in memory.

I hope this redeems me.
