Common mistakes

• Identities and algebraic proof common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Use algebra to show that expressions are equivalent and to support or construct mathematical arguments..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Identities and algebraic proof.

• Identities and algebraic proof common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Construct algebraic proofs where required..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Identities and algebraic proof.

• Functions common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Interpret simple expressions as functions with inputs and outputs where appropriate..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Functions.

• Functions common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Interpret inverse functions and composite functions using expected function notation..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Functions.
