This isn’t a particularly high-tech post, but it helped me out in tricking innocent bystanders of a cell’s true intention. Suppose you are using Excel and want to show someone a nonsensical output from a cell evaluation. You type in something innocuous, like =rand(), which should give a random number between 0 and 1. If you want the “random” number to always be between .5 and .75, however, you could type =rand()*.25+.5. In my case, I wanted to show someone the equation “=rand()” but the output from “=rand()*.25+.5”, so that whenever I updated, it would give a number between .5 and .75. The observer would be confused and hilarity would ensue as the “random” number always falls between .5 and .75. To do this, type “=rand()” at the far left of the cell equation box, like normal. Then put a bunch of spaces until you get to the middle of the equation box, and put “*”. Then put more spaces until you are off the initial screen and type the rest of the equation “.25+.5”. Now, when the equation is viewed, the observer will only see the “=rand()”, unless they are looking very closely and notice the odd multiplication sign in the middle of the line. In my experiments, I have found that Excel will delete your excessive spaces if you only put “=rand()” on the far left and “*.25+.5” off the screen. For some reason, the spaces are not deleted if you type something in the middle of the equation box. Use this information as you will.
