| الأرقام والأعداد الرومانية
وبالمثل ، اعتمد الرومان طريقة مبسطة لكتابة ناتج عملية الجمع (الإضافة) بين عددين ، وذلك يوضع العدد الأصغر إلى يمين العدد الأكبر ويكون الرمز الناتج من تجاور الحرفين هو الرمز الدال على ناتج الجمع أو الإضافة . <table style="border-collapse: collapse;" id="AutoNumber8" border="0" bordercolor="#111111" cellpadding="0" cellspacing="0" width="52%" height="88"> <tr> <td dir="rtl" style="border-style: solid solid none; border-width: 2px 2px medium;" bordercolor="#999966" align="center" width="42%" height="50"> 1 + 5 = 6 </td> <td dir="rtl" width="11%" height="50"> </td> <td dir="rtl" style="border-style: solid solid none; border-width: 2px 2px medium; padding: 1px 4px;" bordercolor="#FF9900" align="center" width="47%" height="50"> 1 + 10 = 11</td> </tr> <tr> <td dir="rtl" style="border-style: none solid solid; border-width: medium 2px 2px;" bordercolor="#999966" align="center" width="42%" height="38">
