# Display mathematical symbols on Writer [closed]

Is there an add-on or extension that I should install to correctly display mathematical symbols on Writer? My teacher sends me docx files with logic formulas using symbols like the material implication (→), the material equivalence (↔), the logical negation (¬), logical conjunction/disjunction and so on, however they don't display correctly.

What is your operating system name/version and LibreOffice version? What do you see instead of "don't display correctly" characters? Do you see some other characters for each of character or do you see square (sign for non existing character font) or something else?
