Og 数学ps 213中有一句话是：then the reciprocal of r is equal to the sum of the reciprocals of x and y.意思是1/r=1/x+1/y.我理解为1/r=1/x+y,我想问一下1/x+y英文咋说。

the sum of y and the reciprocal of x

我没表述清楚T T,
忽然明白了，是不是the reciprocal of the sum of x and y?x+y分之一？
1/x+1/y the sum of the reciprocals of x and y

嗯对
祝考试顺利

是把the sum of the reciprocals的"s"去掉么？求解求解，谢谢。
