Solved Examples on CCXXIII Roman Numerals

Example 1: Calculate the value of CCXX + III in Roman numerals.
Solution: To find the value of CCXX + III, let’s convert it first into numbers:
CCXX = C + C + X + X = 100 + 100 + 10 + 10 = 220  and III = I + I + I = 1 + 1 + 1 = 3
CCXX + III = 220 + 3
CCXX + III = 223
CCXX + III = CCXXIII

Example 2: Write 223 in Roman numerals.
Solution: To write 223 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:
223 = 100 + 100 + 10 + 10 + 1 + 1 + 1
223 = C + C + X + X + III
Hence, 223 = CCXXIII

Example 3: Find the value of CCXXX – VII in Roman numerals.
Solution: To find the value of CCXXX – VII in Roman numerals, first convert it into numbers:
CCXXX = 100 + 100 + 10 + 10 + 10 = 230 and VII = 5 + 1 + 1 = 7
CCXXX – VII = 230 – 7
CCXXX – VII = 223
CCXXX – VII = CCXXIII
