To understand this question we need to analyze the following. In case we wanted to analyze how many times a number is multiplied by a modifier we would not use the plus or minus score. We would also not use them to define the make an emphasis or provide a mood orientation to a certain line of dialogue. Neither to rate someone's opinion of our work. But we could use to fill the spaces of a rubric to rate each category of the criteria.
Plus or minus is a sports statistic used to measure a player's impact on the game,represented by the difference between their team's total scoring versus their opponent's when the player is in the game.In ice hockey,it measures a player's goal differential.
