mid400s

The term "mid-400s" is a colloquial or informal way of referring to a range of numbers or values that fall between 450 and 459, inclusive. It is often used when a precise number is not necessary or when a general approximation is sufficient. For example, one might say they have "mid-400s" of items in inventory, implying the count is somewhere between 450 and 459.

This phrasing is common in everyday conversation and can be applied to various contexts, such as prices, quantities, scores, or measurements. The exact meaning can sometimes depend on the specific context, but the general intent is to indicate a number in the upper half of the 400-499 range. Without further context, "mid-400s" signifies a numerical area roughly centered around 455. It is not a formal mathematical term and lacks a precise, universally agreed-upon definition beyond its approximate numerical location.
