Question 741506
<pre>You made a sign error.

{{{-1&2/3}}}{{{""-""}}}{{{(-1&4/11)}}} 

When you have "minus a negative" you can replace it by
"plus a positive"

{{{-1&2/3}}}{{{""+""}}}{{{(1&4/11)}}}

Multiply the {{{2/3}}} by {{{11/11}}} to get {{{22/33}}}
Multiply the {{{4/11}}} by {{{3/3}}} to get {{{12/33}}}

{{{-1&22/33}}}{{{""+""}}}{{{(1&12/33)}}} 

The signs are different so we subtract the absolute values
    
         {{{(1&22/33)}}}{{{""-""}}}{{{(1&12/33)}}}{{{""=""}}}{{{10/33}}} 

BUT, we MUST take the sign of the one with the larger absolute
value which is {{{-1&22/33}}} so the answer must be NEGATIVE:

Answer: {{{-10/33}}}
