So, there’s this thing called absolute value, or a modulus function that basically says how far away any real number $n$ is from $0$. For example, $|2|=2$ because $2$ is $2$ units away from $0$. Furthermore, a negative number’s $($such as $-3)$ absolute value is simply its positive counterpart. So, $|-3|=3$.
This got me thinking, what is the usage of such a function other than to turn negatives into positives?
Edit: Xander Henderson commented about the Wikipedia article for absolute value, and honestly, the article literally repeats what I already know. This is the case for every video or website I go to. In this post, I want to know if there is any OTHER use for absolute value other than telling an integer’s distance from $0$.
