How should I represent equations in captions?

Captioning equations can be quite tricky, especially when they can include some unusual characters.

Where it is clear and easy to depict, always try to use the equation.

  • E.g. ‘One times n plus one minus x’ is ‘x n + 1 – x’ in captions.

Exceptions

  • ‘Squared’ – Write as a word. E.g. 42– x2 = 16x is ‘4x squared – x squared = 16x squared’ in captions.
  • Chemical equations – Use the subscript/superscript in normal case. E.g. ‘H2O’ is ‘H2O’ in captions.
