I support the calculation of the Dutch treat when there are plural people who rebuilt it.
Rebuilt it no matter how much from a wallet of each person; when input, and push the "Dutch treat calculation" button,
"Refund amount of money" is displayed.
Because amounts of money that "refund amount of money" rebuilt at the time of plus exceed a Dutch treat, I can receive the amount of money share from "somebody".
Because there are fewer amounts of money that "refund amount of money" rebuilt at the time of minus than a Dutch treat, it is necessary to pay the amount of money share to "somebody".
