  7. Functions • Syntax (format) for keying a formula in Excel • All formulas start with an = sign • ADD =B2+A4 or • SUBTRACT =B2-A4 • MULTIPLY =B2*A4 • DIVIDE =B2/A4 • SUM (A1:D8) or @SUM(A1:D8”)

  8. Converting Data into a Charts & Graphs? • Parts of a Chart • Title – describes the content of the chart so there is no confusion • Legend – indicates which colour represents which category • Data labels • X-axis – the horizontal axis of a column chart • Y-axis - the vertical axis of a column chart
