In the Hindu-Arabic numeral system, each digit has a place value based on its position within a number. The rightmost digit represents the ones place, the digit to its left represents the tens place, the next digit to the left represents the hundreds place, and so on. The value of a digit is determined by multiplying it by its place value.

For example, the Hindu-Arabic number “31” consists of two digits: “3” in the tens place and “1” in the ones place. The value of the digit “3” in the tens place is 3 times 10, or 30. The value of the digit “1” in the ones place is 1 times 1, or 1. To find the total value of the number “31,” we add these values together: 30 + 1 = 31.

When we write XXXI in Roman numerals, it represents 30 + 1, or 31, in the Hindu-Arabic numeral system. Therefore, to write XXXI in Hindu-Arabic numbers, we simply use the corresponding digits for 30 and 1, which are 3 and 1, respectively. Thus, XXXI in Hindu-Arabic numbers is 31.

Here are a few more ways to convert XXXI from Roman numerals to Hindu-Arabic numbers:

Additive method:

XXXI can be written as XX + X + I. Using the additive principle, we add the values of each Roman numeral together:
XX = 20
X = 10
I = 1
20 + 10 + 1 = 31
Therefore, XXXI in Hindu-Arabic numbers is 31.

Subtractive method:

XXXI can also be written as XXX – X + I. In this case, we subtract the value of X from XXX and add the value of I:
XXX = 30
X = 10
I = 1
30 – 10 + 1 = 21
However, this method is less commonly used for numbers that are not multiples of ten.

Using conversion table:

Another way to convert XXXI from Roman numerals to Hindu-Arabic numbers is to use a conversion table that lists the values of each Roman numeral. For example:
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000

Using this table, we can break XXXI down into its individual Roman numerals and add their values together:

XXXI = X + X + X + I
= 10 + 10 + 10 + 1
= 31
Therefore, XXXI in Hindu-Arabic numbers is 31.

Here are a few ways to perform mathematical operations with XXXI:

Addition:
To perform addition with XXXI, you can simply add the number to another number. For example, XXXI + 5 = 36.

Subtraction:
To perform subtraction with XXXI, you can subtract another number from it. For example, XXXI – 10 = 21.

Multiplication:
To perform multiplication with XXXI, you can multiply it with another number. For example, XXXI x 2 = 62.

Division:
To perform division with XXXI, you can divide it by another number. For example, XXXI ÷ 3 = 10.33 (rounded to two decimal places).

It’s important to note that while these mathematical operations can be performed with XXXI, it is not a commonly used number for mathematical operations. Hindu-Arabic numerals are generally used for mathematical calculations, while Roman numerals are primarily used for symbolic representation and in contexts such as clock faces and movie credits.

The Roman numerals related to XXXI are given below:

XXX = 30
XXXI = 30 + 1 = 31
XXXII = 30 + 2 = 32
XXXIII = 30 + 3 = 33
XXXIV = 30 + 4 = 34
XXXV = 30 + 5 = 35
XXXVI = 30 + 6 = 36
XXXVII = 30 + 7 = 37
XXXVIII = 30 + 8 = 38
XXXIX = 30 + 9 = 39
