Question

Write the following Roman Number in Hindu-Arabic numerals:

$\mathrm{MCDXLIV}$

Answer 1

In the Roman Numerals system, there are seven basic symbols to write any numeral. The symbols are given below:

Roman Numerals	$\mathbf{I}$	$\mathbf{V}$	$\mathbf{x}$	$\mathbf{L}$	$\mathbf{C}$	$\mathbf{D}$	$\mathbf{M}$
Hindu- Arabic Numerals	$\mathbf{1}$	$\mathbf{5}$	$\mathbf{10}$	$\mathbf{50}$	$\mathbf{100}$	$\mathbf{500}$	$\mathbf{1000}$

With the help of the above table, we can write the value in Hindu Arabic Numerals as:

$\therefore$ $\mathrm{MCDXLIV}=1000+\left(500-100\right)+\left(50-10\right)+4$

• A smaller numeral appearing to the left of a larger numeral is always subtracted from the larger numeral, So, $\mathrm{XL}=50-10=40$ and $\mathrm{CD}=500-100$

$\therefore \mathrm{MCDXLIV}=1000+400+40+4$

$=1444$

Therefore, the answer is $1444$
