By selecting cell C1 and dragging the formula down to C5 the below formulae will be replicated in C2 to C5: (A2*B2), (A3*B3), (A4*B4) and (A5*B5)
- Formulas are used to signify a mathematical function
e.g. = (C5 * D5) * 100
= A5 + B5 + C5+ D5
- Functions allow computations to take place
For instance SUM, AVERAGE, MAX, MIN
