Order of operations (BIDMAS/BODMAS)

What is the order of operations (BODMAS/BIDMAS)?

  • If there is more than one operation in a calculation then they should be done in the following order

    • Brackets: ( )

      • Perform any calculation(s) inside brackets first

    • pOwers or Indices (sometimes Order): 2, 3, √ and similar

      • These include powers, roots, reciprocals

    • Divisions or Multiplications: × or ÷

      • If there are more than one of these then work them out left to right

      • Division includes fractions

    • Additions or Subtractions: + or –

      • If there are more than one of these then work them out left to right

  • The acronym BODMAS or BIDMAS can help you remember the order of operations

In what order should fractions and roots be dealt with?

  • Fractions mean division in calculations (BODMAS/BIDMAS)

  • There may be “invisible brackets” around the numerator and around the denominator

    • e.g. fraction numerator 2 plus 5 over denominator 7 minus 2 end fraction means open parentheses 2 plus 5 close parentheses divided by open parentheses 7 minus 2 close parentheses

    • Instead of brackets we extend the fraction line to show exactly what is on the top and what is on the bottom

  • Roots are pOwers (BODMAS/BIDMAS)

  • There may be “invisible brackets” under the root

    • e.g. square root of 9 plus 16 end root means square root of open parentheses 9 plus 16 close parentheses end root

    • Instead of brackets we extend the top line on the root symbol to show everything that is to be rooted

How do I use a calculator for BIDMAS/BODMAS questions?

  • Ensure that you enter a long or complicated calculation carefully

    • For most modern calculators, the calculation can be typed in exactly as it is written on paper 

    • You may need to use additional brackets on older calculators

Examiner Tips and Tricks

  • Make sure that you always check that your answer seems sensible!
