Math is the LibreOffice suite's formula editor, that can be invoked in your text documents, spreadsheets, presentations and drawings, to enable you to insert perfectly-formatted mathematical and scientific formulas. Your formulas can include a wide range of elements, from fractions, terms with exponents and indices, integrals, and mathematical functions, to inequalities, systems of equations, and matrices.
