**Formulae**

Used to perform calculations on cell contents

- In order to distinguish between text and formulae a symbol = needs to be typed in first

**Functions**

Specialised calculation that the spreadsheet software memorised. A function must start with an = sign and it must have a range of cells to which it applies in brackets after it.

- AVERAGE: =AVERAGE(A3:A10)
- MAXIMUM: =MAX(D3:J3) displays the largest number in all the cells from D3 to J3 inclusive
- MINIMUM: =MIN(D3:J3) displays the smallest number in all the cells from D3 to J3 inclusive
- MODE: =MODE(A3:A15) most frequenct number in the cells
- MEDIAN: =MEDIAN(B2:W2)
- SUM: =SUM(E3:P3) displays total of all cells
- ROUND: rounds a number correct to a number of digits that you specify, ROUND(number, number of digits) where the number is the number you want rounded off and the number of digits is the number of decimal places e.g, =ROUND(3.56678,2) = 3.57
