Now, many people make a big deal out of having to do out the entire chart, and to some it helps with the focus. However, a sum of a string of numbers is a sum of the string of numbers no matter how you stack the same numbers (another example of this can be seen at the top of the page). In other words…just add them up! Some folks find it easier to do the math if they stack the name one letter per line on lined paper vertically rather than writing it out horizontally. It is absolutely fine to use a calculator!
