Answer key: Roman Numeral worksheet

1. Number: 1,994
1. Split the numeral into pieces. A smaller symbol right before a larger one is read as one piece, the larger minus the smaller
  $M = 1,000, CM = 900, XC = 90, IV = 4$
2. Add the values of the pieces
  $1,000 + 900 + 90 + 4$ $= 1,994$
2. Roman numeral: MMDCCC
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,800$ $= 2,000 + 800$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Write 800 with the symbols for its place
  $800 → DCCC$
4. Join the pieces from largest to smallest
  $MM + DCCC = MMDCCC$
3. Roman numeral: MMCD
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,400$ $= 2,000 + 400$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Write 400 with the symbols for its place (a subtractive pair: the smaller symbol comes first and is taken away)
  $400 → CD$
4. Join the pieces from largest to smallest
  $MM + CD = MMCD$
4. Roman numeral: MDC
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $1,600$ $= 1,000 + 600$
2. Write 1,000 with the symbols for its place
  $1,000 → M$
3. Write 600 with the symbols for its place
  $600 → DC$
4. Join the pieces from largest to smallest
  $M + DC = MDC$
5. Roman numeral: MDCCCL
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $1,850$ $= 1,000 + 800 + 50$
2. Write 1,000 with the symbols for its place
  $1,000 → M$
3. Write 800 with the symbols for its place
  $800 → DCCC$
4. Write 50 with the symbols for its place
  $50 → L$
5. Join the pieces from largest to smallest
  $M + DCCC + L = MDCCCL$
6. Roman numeral: MMCC
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,200$ $= 2,000 + 200$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Write 200 with the symbols for its place
  $200 → CC$
4. Join the pieces from largest to smallest
  $MM + CC = MMCC$
7. Roman numeral: MMD
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,500$ $= 2,000 + 500$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Write 500 with the symbols for its place
  $500 → D$
4. Join the pieces from largest to smallest
  $MM + D = MMD$
8. Roman numeral: MDCCC
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $1,800$ $= 1,000 + 800$
2. Write 1,000 with the symbols for its place
  $1,000 → M$
3. Write 800 with the symbols for its place
  $800 → DCCC$
4. Join the pieces from largest to smallest
  $M + DCCC = MDCCC$
9. Roman numeral: MM
1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,000$ $= 2,000$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Join the pieces from largest to smallest

1. Split the number into its place values (thousands, hundreds, tens and ones)
  $2,100$ $= 2,000 + 100$
2. Write 2,000 with the symbols for its place
  $2,000 → MM$
3. Write 100 with the symbols for its place
  $100 → C$
