Question 1168577
.


The formulas in your post are written in  AMBIGOUS  way.


For example,   I can read    y/x-z    as    y/(x-z)    or    as    (y/x) - z.




THEREFORE,  when you post the formulas to this forum,  use parentheses


properly and systematically to show every time,  which part of the expression


is the numerator and which is the denominator.




So,  edit your formulas and re-post to the forum.


Please do not post it to me personally.
