Frequently asked questions

- Percent of a value, what-percent-is-X-of-Y, percentage increase, percentage decrease, discount, tax, tip, margin, and markup.
- Can I split the tip and bill among a group?
- Yes - in Tip mode, enter the number of people and the total (your amount plus the calculated tip) is divided evenly to show what each person owes.
