They won 15 and each got 5 points so 15 x 5 = 75 points
They drew 3 and each got 1 point so 3 x 1 = 3 points
They lost 3 matches and each got -2 so 3 x -2 = -6
Altogether they got 72 points as 75+3-6=72
However they started on -14 so 72-14 equals 58 therefore at the end of the season they had 58 points
Hope this helps !
