This tweet from a while back prompted this short little post.
Here is the standard Windows calculator that we have all used hundreds of times. I often have about 5 instances of it open at any one time (and have of course forgotten what half of them represent). I’m pretty sure everyone does this, but a quick way to open it is: Windows Key –> R –> Calc –> Enter. You can usually skip typing Calc because it will still be there.
But did you know that this calculator does other [very cool] stuff too?
Then there are a bunch of templates (worksheets).
