Generally I let the nerd herd (aka our talented team of web developers) be the ones to get excited about math related functionality. However, I gotta say, I do get excited about the way InDesign allows you to do math in the control panel. Probably because anything that does the math for me is exciting! How does it work? Imagine you have a frame with an image in it on the page and you know that it would probably fit better if it were 2.125″ bigger. In the Width field up in the Control panel, type +2.125 next to the existing size. When you’re done, press Tab or Return (PC: Enter) and InDesign will do the math for you to adjust the size of your frame. This also works in the X and Y axis fields — allowing you to move items by a specified amount without doing the math yourself. You can also use different functions, such as subtraction (–), multiplication (*), and division (/).
