How to Show a Paper Tape in Calculator App for Mac
If you find yourself adding up many numbers or just performing a continuous string of math that is critical to keep track of, you should know that the Mac Calculator app includes a paper tape feature. For those who aren’t familiar, a paper tape keeps a running trail of each item entered into a calculator, making it easy to follow and audit anything in the calculation. Obviously useful for many occasions, the deceptively simple Calculator app in OS X includes this ability, and you can also save and print the generated number tape if desired.
