Conversation

I think my answer is just an approximation of the real value.

That's okay! Sometimes we just need a rough idea to move forward.

I'm sure it will be fine; we can always adjust it later.

Root Explanation

Approximation → It is formed from "ad-" (meaning to) and "proximare" (meaning to be near). The word refers to the act of coming close to a value or idea, hence suggesting nearness or similarity.

Memory Tip

Think of getting 'close to' something ('ad-') and being 'near' ('proximare') — that's why approximation means getting close to a value.
