![Is Writing 2K13 Technically Correct? [Closed]](https://docuprint.cloud68.co/uploads/is-writing-2k13-technically-correct-closed_1200.jpg)
As seen in the video game title NBA 2K13, they have used 2K13. But is it technically correct? I think that 2K13 => 200013!
EDIT: Sorry for the wrong reference to Roman Numerals

The use of K as an abbreviation for $1000$ has nothing to do with Roman numerals: the Roman numeral for $1000$ is M. It derives from the prefix kilo-, used in the metric system to indicate $1000$ of some base unit. It is a non-standard usage, so there is no standard of technical correctness. In this case you should think of the K simply as an abbreviation for thousand and read it two thousand thirteen.
- $K\neq \text{''000''}$
- K does not correlate whatsoever with the roman numerals.
- In decimal notation, numbers are written as $\sum_{k=-\infty}^{\infty}a_n10^n$, therefore, 2K13 is not technically correct if we are using the standard decimal notation. Here it is to mean $2*K+13$ where $K=1000$
No, it is not “wrong”. The sense in which $\rm K$ is used here is indisputable because it is only a video game title, not to be taken too seriously. What they meant here was $\rm 2K + 13$.
Roman numerals are not connected with the metric system whatsoever. $\rm K$ belongs to the metric system, and $\rm M$ is the real Roman numeral for 1000.
