Prepare to have your mind bent. Logarithms are the secret, opposite world of exponents.

An exponent asks: 'What do I get if I multiply this number by itself X times?' (2³ = 8)

A logarithm asks the opposite, more profound question: 'How many times must I multiply this number to get X?' (log₂8 = 3)

They are the secret to taming massive, exponential numbers and bringing them down to a human scale.

The Richter scale for earthquakes? That's logarithms. Decibels for sound? Logarithms.

They are a way to ask, 'What was the power that created this result?'

Every rule for exponents has a mirror-image rule for logarithms. They are a perfect duality.

Mastering logarithms feels like you've been given a key to a secret, hidden level of mathematics.

They are the tool you use when numbers become too astronomically large to comprehend.

They are a mind-bending, powerful, and essential secret. And now, you're in on it.
