99+1056 = 1155 or MCLV in Roman numerals
Today we write out 99 in Roman numerals as XCIX but the Romans themselves would have probably wrote it out simply as IC (-1+100 = 99)

XIII (13)
In Roman numerals six (10-1.5) is equal to viiis (8.5) So: viiis+viiis = xvii which is the equivalent of 17 in Hindu-Arabic numerals Roman numerals are normally arranged in block capital letters but this computer for some reason won't allow it.
In Roman numerals, "VX" is not a standard representation. Roman numerals typically do not allow for a numeral to precede a larger numeral like "V" (5) before "X" (10). The correct representation for 15 is "XV," which combines 10 (X) and 5 (V) to indicate their sum.
Adding them together in sequence - you get 10+100+100+100+10+100+1+5=426 426 in roman numerals is CDXXVI

The sum of the Roman numerals: V+XL+XLV = XC (90)

38 x 43 = 1634 which in Roman numerals is MDCXXXIIII Multiplying XXXXIII (43) by XXXVIII (38) in Roman numerals: XXXXIII*XXXVIII = XXX(XXXX+III)+VIII(XXXX+III) Multiplying out the brackets = MCC+LXXXX+CCCXX+XXIIII Total sum of numerals = MDCXXXIIII (1634) By separating the numerals into tens and units makes multiplication a lot easier. In a way this is what we do today when tackling long multiplication.
Roman numerals are a numeral system of ancient Rome based on letters of the alphabet, which are combined to signify the sum of their values.
1 + 5 + 10 + 50 + 100 + 500 + 1000 = 1666 (MDCLVI)
With great difficulty because 1444 in Roman numerals in today's terms are MCDXLIV and to add them to DLV (555) is an almost impossible task. But the Romans probably calculated the above numbers on a abacus calculating board as:- MCCCCXXXXIIII + DLV = MDCCCCLXXXXVIIII = IMM (-1+2000=1999) when simplified. The rules governing today's Roman numeral system were not the same rules in which the Romans themselves actually used because they were changed in the Middle Ages presumably to make it easier to convert Roman numerals into Hindu-Arabic numerals that were gradually being introduced into Western Europe.
LXV represents the number 65 in Roman numerals. It is formed by combining the symbols L (50), X (10), and V (5), which together sum to 65. Roman numerals are a numeral system originating from ancient Rome, using combinations of letters from the Latin alphabet.
If you mean the roman numerals, then IX = 9 and XI = 11, and 11+9=20 which can be written as XX.
