Sports calculators
Box scores, standings and fight cards are full of numbers that are easy to quote and harder to work out yourself: an earned run average, a passer rating, a magic number, a judge's scorecard. These calculators do the arithmetic the official way and show each step, so you can check a broadcast graphic or settle an argument with a friend.
Each page names the rule or formula it follows, such as the 10-point must system for boxing and MMA judging or a league's points table, and notes where leagues and commissions differ. Official results always come from the governing body, not from a calculator.
