在加减乘除四则运算中,加法是最简单的,任何数加零还等于这个数,无所失也无所得。但在举重比赛中,运动员的比赛成绩却不是这样计算的。它是抓举和挺举两项分数之和,但只要抓举和挺举中有一项成绩为零,那么,运动员的总成绩就为零。这时,它就像乘法中的零一样,与任何数相乘都等于零,不管你的另外一项成绩有多好,败局已定。
Addition, subtraction, multiplication and division of four operations, the addition is the most simple, any number plus zero also equal to this number, no loss or no gain. However, in the weightlifting competition, the athlete’s performance is not calculated in this way. It is the sum of both snatch and jerk, but as long as one of the snatch and jerk scores is zero, the athlete’s overall grade is zero. At this point, it’s like multiplying zeros and multiplying any number by zero equals zero, no matter how good your other grade is.
