PE4MA Roman numbers Hard

Roman numerals are a system for writing numbers using letters of the alphabet.

The numbers represented by the Roman numerals I, V, and X (1, 5, and 10).

When a smaller Roman numeral is placed to the right of a larger one, their values are added together.

When a smaller Roman numeral is placed to the left of a larger one, its value is subtracted from the larger one.

The numeral 'I' can be repeated up to three times to form the numbers 1, 2, and 3.

The Roman numeral 'I' cannot be repeated more than three times in a single number.

Other Roman numerals from 4 to 9 are formed using combinations of I, V, and X, following the rules of adding and subtracting.

The highest value Roman numeral in this list of Roman numbers is XV, with a total of 15.

XIV stands for 10 + 4. XVI stands for 10 + 6. XX stands for 20. XI stands for 10 + 1. XV stands for 10 + 5. XIX stands for 10 + 9.

The value of the Roman numeral VI is 6, and the value of Roman numeral VII is 7. Combining these into a single number makes 6 + 7 = 13.

The number 28 in Roman numbers is XXVIII, since 28 = 20 + 8, and the Roman numbers for 20 and 8 are XX and VIII respectively.

The Roman numeral XXX is the next largest Roman numeral after XXIX, representing 30, making the sequence XXI, XXIII, XXV, XXVII, XXIX, XXXI, XXXIII.

The Roman numeral XXIV is 24, and the Roman numeral XXVI is 26. Since the Roman number for 25 is XXV, the sequence becomes XXIV, XXV, XXVI, XXVII, XXVIII, XXIX, XXX, XXXI, XXXII, XXXIII...

The Roman numeral XXXII is 32, and the Roman numeral XXX is 30. Therefore, the sequence is XXXII, XXXI, XXX, XXIX, XXVIII, XXVII, XXVI.

Following the sequence, the Roman numerals should be XXIV, XXIII, XXII, XXI.

XLIV is 44, XXXIX is 39, XXXV is 35, and XLVI is 46.

XXXIV represents 30 + 4, which is 34. Remember, the smaller numeral 'IV' to the right of 'XXX' represents 4, not 6.

XLVIII represents 40 + 8, which is 48. The 'XL' represents 40, and 'VIII' represents 8.

XLI represents 40 + 1, which equals 41. The 'XL' represents 40 and the 'I' represents 1.

XXXIV represents 30 + 4, which equals 34. 'XXX' is 30, and 'IV' is 4.

The missing numbers are XXXV (35) and XXXVII (37). The pattern is adding one each time.

The missing numbers are XL (40), XLIV (44), XLVIII (48) and XL (40), XLII (42), XL (40) and XXXIV (34). The sequence starts with 36 (XXXVI) and adds 2, adds 2, adds 2, then keeps repeating this pattern.

The missing numbers are XLV (45), XLVI (46), XLVII (47), XLVIII (48), XLIX (49) and XLII (42). The sequence starts with 50 (L) and counts down 5, then 2, then 2. It then goes up to 40 (XL) and keeps going down by 2, then counting up to 25 (XXV).

The missing numbers are XXXIX (39) and XLIII (43). The sequence starts with 35 (XXXV) and adds two each time.

The missing numbers are 38 (XXXVIII), 42 (XLII) and 44 (XLIV). The empty spaces in the table represent the missing numerals for the given Roman numbers.

The missing numbers are XXXIII (33) and XXXVIII (38). The sequence starts with 32 (XXXII) and adds 4 each time.

The Roman numeral 'D' represents 500 and 'L' represents 50. Therefore, 'DL' represents 500 + 50 = 550.

The Roman numeral 'C' represents 100. When placed before the 'M' (1000), it subtracts from M, resulting in 1000 - 100 = 900.

To convert 576 to Roman numeral, break down the number into simpler parts: 500 + 70 + 6. The Roman numerals for these parts are 'D', 'LXX', and 'VI', respectively. Therefore, 576 is represented as 'DLXXVI'.

The Roman numeral 'C' represents 100. When placed before the 'D' (500), it subtracts from D, resulting in 500 - 100 = 400.

To convert the Roman numeral 'CDLXXVIII' to numerals, break down the Roman numeral into its component parts: 400 + 50 + 70 + 8 = 528.

The Roman numeral for 100 is C. A hundred and one would be CI. A hundred and twenty-five would be CXXV. You can add the values of Roman numerals placed to the right of each other.

The Roman numeral for 500 is D. Five hundred and ten would be DX. Note that C is less than D, so CD represents 'four hundred'.

LXXX means 80 (L = 50, X = 10, 80 = 50 + 10 + 10 + 10). So, LXXXI means 81, LXXXII means 82, and so on.

CCC is for 300. A hundred and fifty would be CL. Since L is less than C, it's positioned before C to indicate subtraction.

CCXXV means 225 (CC is 200 and XXV is 25). Think of CCXXV as two hundred and twenty-five, breaking it down into smaller parts.

CD means 400, XL means 40. D is positioned before the smaller numeral, so we subtract 100 from 500 (D) to get 400.

The Roman numeral for 500 is D. Five hundred and one would be DI. Five hundred and twenty-five would be DXXV.

To write 444 in Roman numerals, start by thinking of the next larger number: 500 (D). 400 can be represented as CD (D - C = 400). Then, add four more: CDXLIV.

Remember that Roman numerals follow a set of rules: Smaller Roman numerals placed to the right of a larger numeral add up, smaller numerals placed to the left subtract from the largest.

You can only subtract a smaller numeral from one that is up to ten times larger. You can subtract I from V or X (5,10). You can subtract X from L or C (50,100), and C from D or M (500, 1000).
