Find your way around the Excel window

  • Ribbon: the tabs at the top (Home, Insert, Formulas, Data ...). Home holds fonts, number formats and alignment.
  • Name Box (left of the formula bar) shows the active cell, e.g. D2. Type a cell address there and press Enter to jump to it.
  • Formula bar: shows what is really in the cell. The cell shows 298.80, the bar shows =B2*C2.
  • Fill handle: the small square at the bottom right of a selected cell. Drag it down (or press Ctrl+D) to copy a formula to the rows below.

Format numbers, don't round them by hand

Select the cells and press Ctrl+1 (Mac: Cmd+1) to open Format Cells. Choose Number with 2 decimals and the thousands separator, Currency, or Percentage. Formatting only changes how a value looks. The cell still holds the full value, so totals stay exact.
