What is MMXXI in Roman Numerals?
The Roman numerals MMXXI are the equivalent of the number 2021. As we are now in the 21st century, they have been used quite a lot recently to express the year 2021, which is one of the most common uses of Roman numerals these days since they fell out of favor and largely replaced by the Arabic numerals that are more familiar to us in everyday life today.
How Do We Get 2021 From MMXXI?
As we saw on our main Roman numerals page here at UNRV.com, whenever the same or a smaller number comes after a larger one, it is added to the previous one. When it comes to the expression MMXXI, we convert it to the number 2021 in the following way:
M (1000) + M (1000) + X (10) + X (10) + I (1)
this works out as: 1000 + 1000 + 10 + 10 + 1 = 2021!
Although it looks quite complicated with 5 letters in total, the Roman numeral MMXXI is actually one of those nice, easier ones to work out as there are no larger numerals coming after a smaller on, so nothing needs to be subtracted. This means that MMXXI is a simple addition equation, as evidenced in the working out above.
