A football team has these results in four plays; a loss of 3 meters, a gain of 9 meters, a loss of 6 meters and a gain of 17 meters, Find the total number of meters lost or gained.
We add all of these so the expression will be [tex](-3)+9+(-6)+17 \\ =-3+9-6+17 \\= 17[/tex] (A loss has a negative sign and a gain has a positive sign)
Therefore the meters gained is 17 (since 17 is positive).
