Creating report using single Dax

I want to create a report using single dax.

In dax i used different variablies like  

VAR category = VALUES(Orders[Category])

VAR sub_category = VALUES(Orders(sub-category])

VAR products = VALUES(Orders[Products])

VAR total_sales = SUMX(Orders , Orders[Sales])

VAR avg_sales = AVERAGEX(Ordres , Orders[Sales])

VAR result = ???? (I want to add all these VAR in result to show as report)

RETURN result
