英文小作文：

Title: Approximate vs. Exact

When we talk about numbers, we often use the words approximate and exact. Although they seem similar, they have different meanings and usages.

Approximate means roughly or roughly close to the actual number or amount, while exact means completely accurate and precise. We use approximate when we don"t have the exact information or when we don"t care about the exact number as long as it"s close enough.

For example, if we say "the size of the room is approximately 20 square meters", it doesn"t mean that the room is exactly 20 square meters, but it"s close enough for our needs. On the other hand, if we say "the price is exact", it means that we have the exact price and there"s no approximation involved.

In real life, we use approximate and exact in different situations and for different purposes. Sometimes we need to be more flexible and accept a slightly different number or amount, while other times we need to be precise and accurate to avoid any mistakes or misunderstandings. Therefore, it"s important to use the correct word based on the context and purpose of the conversation or writing.
