Question 173054
I understand the confusion.
Sometimes it's better to keep the numbers separated and not combine them.
This is one of those cases.
{{{(sqrt(6)+sqrt(5))*(sqrt(6)-sqrt(5))=(sqrt(6)*sqrt(6))-(sqrt(6)*sqrt(5))+(sqrt(5)*sqrt(6))-(sqrt(5)*sqrt(5))}}}
{{{(sqrt(6)+sqrt(5))*(sqrt(6)-sqrt(5))=(sqrt(6)*sqrt(6))-cross((sqrt(6)*sqrt(5)))+cross((sqrt(5)*sqrt(6)))-(sqrt(5)*sqrt(5))}}}
{{{(sqrt(6)+sqrt(5))*(sqrt(6)-sqrt(5))=(sqrt(6)*sqrt(6))-(sqrt(5)*sqrt(5))}}}
{{{(sqrt(6)+sqrt(5))*(sqrt(6)-sqrt(5))=6-5}}}
{{{(sqrt(6)+sqrt(5))*(sqrt(6)-sqrt(5))=1}}}
