title: Sum of cell above and cell to the left
body: <p>Don't know if it's the right place, but please help me if possible.</p>
  
  <p>Google Sheets. I need a formula for the sum of value in cell directly above and cell directly to the left. I've tried something like this, but it doesn't work:
  =SUM(INDIRECT(ADDRESS(ROW()-1,COLUMN()), ADDRESS(ROW(),COLUMN()-1)))</p>
