Question

Write the following Roman number in Hindu-Arabic numerals

:$\mathbf{CCXLVIII}$

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:

$\mathrm{CCXLVIII}=100+100+(50-10)+8$ ($\because$A smaller numeral appearing to the left of a larger numeral is always subtracted from the larger numeral, $\mathrm{XL}=50-10=40$)

$=200+40+8$

$=248$

Therefore, the answer is $248$
