        <p id="par_id111584200892379" class="paragraph" dir="auto">El propòsit principal del LibreOffice Math és crear fórmules matemátiques, però també pot utilitzar-se per a escriure fórmules químiques. A diferència de les matemàtiques, en les fórmules químiques els símbols normalment s'escriuen en majúscules amb lletres rodones, no en cursiva.</p>
