求翻译：矢量减法是矢量加法的逆运算，一个矢量减去另一个矢量，等于加上那个矢量的负矢量。A-B=A+(-B)。②物理定律的矢量表达跟坐标的选择无关是什么意思？ 待解决

Vector subtraction is the inverse of vector addition, subtract a vector to another vector, equal to that vector with a negative vector. AB = A + (-B). ② expression vector laws of physics has nothing to do with the choice of coordinates

Vector subtraction is the law of vector reverse calculations, and a vector minus another vector, the vector is equal to the negative vector. - B A B = A+ ( - ). 2 physical law of expression vector coordinates with no bearing on the choice

Vector subtraction is the inverse of vector addition operation, one vector minus another vector, equal to the negative vector together with the vector. A-B=A+(-B)。 ② physical laws regardless of selected expression vector with coordinates
