Definition

A number that results from applying the inverse operation of a logarithm; it is the original number for which the logarithm was calculated.

Example

To find the antilogarithm of 2, you would calculate 10 raised to the power of 2, which equals 100.

Conversation

Have you ever tried to calculate the antilogarithm of a number?

No, I haven't! Isn't it just the opposite of finding the logarithm?

Exactly! So if you know the logarithm, you can find the antilogarithm easily.

That sounds useful, especially in math class.

Root Explanation

Antilogarithm is formed from "anti-" (meaning against or opposite) and "logarithm" (from Greek "logos" meaning ratio and "arithmos" meaning number). The term refers to the inverse operation of a logarithm, essentially providing the original number from its logarithmic form.

Memory Tip

Think of 'anti-' meaning 'opposite' and 'logarithm' relating to a 'number' — an antilogarithm gives you the original number that corresponds to a logarithmic value.
