Question 1090272
.
I can not read your post.


Is  -5/5n    this term:   (-5)/(5n)  ?


Or this:   ((-5)/5)*n  ?


To avoid ambiguity,  use parentheses.



It is the only way to make your formulas readable.



Using parentheses in formulas is &nbsp;<U>the rule</U>&nbsp; of this forum.



So, &nbsp;re-write and re-post your problem.
