Thus 'dhana', fortunes, is used to represent positive numbers, whereas 'rina', debts, were negative. <br /> Opnieuw verwijzend naar het grote werk van Brahmagupta, alle nodige regels voor de algebra, met inbegrip van de 'tekenregels', waren hierin opgesteld, maar in een vorm die de taal en de beeldtaal van de handel en de markt gebruikte. Dus wordt 'dhana', fortuinen, gebruikt om positieve getallen weer te geven, terwijl 'rina', schulden', voor negatieve getallen wordt gebruikt.</span> </li> <li id="cite_note-5"><span class="mw-cite-backlink"><a href="#cite_ref-5">↑</a></span> <span class="reference-text"><a href="/wiki/Fibonacci" title="Fibonacci">Fibonacci</a>.
