Quick Summary

An antilogarithm is the number that corresponds to a given logarithm. In simpler terms, if a logarithm is the exponent to which a base must be raised to produce a number, the antilogarithm is that resulting number.123

For example, if the base is 10, the logarithm of 100 is 2 because 102 = 100. Therefore, the antilogarithm of 2 (with base 10) is 100.3

Logarithms were historically used to simplify complex calculations, such as multiplication, by converting them into addition. Finding the antilogarithm was the final step in these calculations, retrieving the original number from its logarithm.3
