You are my programming class! Let's dive into the story of how to use the `remove_negatives` function in Haskell for some practical examples. First, we need to understand what a negative number or float is, and why it can be problematic if not handled properly. A negative number or floating point (floating-point number) means that it's less than zero. In this case, the `remove_negatives` function in Haskell might raise an error when trying to find the largest element of a list where the first item is 0 and all subsequent comparisons are thus impossible because you can not take logarithmic root of negative numbers (or complex numbers) or get the square root of NaN, undefined behavior for floating-point numbers. Here'easy ways to address this in Haskell: 1. Use pattern matching.
