2.5.1 Rearranging Formulae - Basics

Choosing a method

  • There are lots of different ways of remembering what to do when rearranging formulae – every teacher (and student) has their favourite, this is my recommendation….


  • This is a mnemonic (way of remembering something) deals with everything except roots and powers (see the following set of notes for that) and can also be used for solving equations…

    1. GROF – Get Rid Of Fractions
    2. GROB – Get Rid Of Brackets
    3. LET – Lump Everything Together (or Let’s Examine Terms)
    4. FIN – Factorise If Necessary
    5. D – Divide
