P81 table midpoint operator in the book of the left operand to the left value



Whereas P201 described in the book said * p value, namely x (x) Can be used as a point of the operator of the left operand


I don't think I understand the wrong, write very understand,
Q: point of operator of the left operand is left or right value?
