• Write numbers using numerical symbols (1, 2, 3…)
  • Don’t use Roman numerals
  • Do not use percentages. If you want to use percentage, make sure that the reader already understands the concept
  • When it is necessary to write the date, do not write it in abbreviated form. Write the day in numbers, the month in letters, and the year in numbers
  • If necessary, use phrases like “long ago” instead of a date to refer to the past
  • Write addresses as they should appear on an envelope (not on one line)
  • If necessary, use phrases like “too many” instead of large numbers
