BODMAS - Order of Operations
When using formulae you must follow the BODMAS order of operations. Without the rule more than one answer could be achieved.
The diagram (left) shows the order to follow:
Brackets: Complete any calculations in brackets first
Orders: Refers to powers
Division: Division is equally weighted with multiplication. Start on the left and work them out in the order you find them.
Multiplication: As division
Addition: Addition is equally weighted with subtraction. Start on the left and work them out in the order you find them.
Subtraction: As subtraction
