Question 387412
{{{(w/w)+(w/23)-(2/w)-1}}}
First of all, w divided by w has to be 1, because any number divided by itself is one. 
{{{(1)+(w/23)-(2/w)-1}}}
Now, we have two terms which say 1 and negative 1.
These, obviously, cancel each other out.
{{{(w/23)-(2/w)}}}
This is as far as it can be simplified.
