These are not my words but I think it would add to the conversation. I found it on quora. I'll watch the video and respond from my own experience. Numbers are an arithmetical esteem, communicated by a word, sign, or figure, symbolizing to a specific value and utilized as a part of tallying and making computations, and for demonstrating requests in an arrangement. They're not "real", they're un-materialistic conceptual elements theoretically existent in our metaphysical creative ability. Mathematics is an array of algorithmic equations used to harness the fictional idea that is ‘numbers’. Arithmetic is natural because it’s an experimentally unavoidable practice, however isn't “real” in light of the fact that it's built upon an ontological premise. Real: “actually existing as a thing or occurring in fact; not imagined or supposed.” - Oxford English Dictionary Reality as a concept is dependent and requires the presence of an alternative term so as to establish its own meaning, validity, purpose and reason. You can't have words like "real" and not have words like "unreal", the pair depend on one another to make sense and exist. So if abstract entities aren't ‘unreal’, then what is? Wouldn’t the contrariety between imagination and reality be conflated? Math is fictive reason.
