  • AVERAGE is another common one which will give you the average of a set of numbers
  • 99 times out of a 100 the questions will relate to the SUM function in the exam
  • The questions in the exam may ask you to create a function that will add up a set of values
  • Remember to start with an equals then the word SUM, then open brackets and include cells that you want to add up, sparated by a colon, and then close brackets
  • I.e. =SUM(B3:B10)

Absolute cell references

  • If you want to stick to the same cell, regardless of how you drag or copy it then you can use an "Absolute cell refernce" like this
  • =$A$1
  • The $ tells the spreadsheet not to alter the formula as you drag or copy it to another cell
  • Absoulute cell references are particualry useful for referencing constant values (i.e., values that never change)
