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.
