Formulas

• Use MathML or LaTeX: MathML is a markup language for describing mathematical notation and capturing both its structure and content. LaTeX is a document preparation system that includes a markup language for creating mathematical and scientific formulas. Both languages can create math formulas that are friendly to screen readers.
  - MathML Example:

                              
                                  <math xmlns="http://www.w3.org/1998/Math/MathML">
                                  <mi>a</mi><mo>+</mo><mi>b</mi>
                                  </math>
                              
                          

  - LaTeX Example:

                              \\[a + b\\]
                          

• Provide Text Alternatives: For complex mathematical formulas, it's important to provide a text explanation so that users who are blind or visually impaired can understand the formula.
