Why Roman numerals matter
Roman numerals often appear in 11+ Maths exams. Children may be asked to read, write, or perform simple calculations using these ancient symbols. Understanding Roman numerals helps build confidence with number systems and strengthens problem-solving skills.
Building the basics
Roman numerals use seven main letters: I for 1, V for 5, X for 10, L for 50, C for 100, D for 500, and M for 1000. Numbers are formed by combining these letters. For example, XX is 20, and IX is 9.
Worked example
Let's add XXIV and XVI.
Step 1: Convert each numeral to Arabic numbers. XXIV is 24. XVI is 16.
Step 2: Add the numbers. 24 + 16 = 40.
Step 3: Convert the answer back to Roman numerals. 40 is XL.
So, XXIV + XVI = XL (40).
Practice tips
Encourage your child to write out the values of each symbol before solving. Use small steps: convert, calculate, and then convert back. Regular practice with different examples builds speed and accuracy.
Key insight: Practising Roman numerals alongside standard numbers helps children spot patterns and check their answers. This makes it easier to avoid common mistakes and boosts exam confidence.
