Logarithms are everywhere in mathematics and derived fields, but we rarely think about how trigonometric functions, exponentials, square roots and others are calculated after we punch the numbers into ...

What they are: A logarithm is the exponent you raise a base to in order to get a number, acting as the inverse of exponentiation. Why they matter: They simplify multiplication, division, and roots ...

👉 Learn how to evaluate basic logarithms. Recall that the logarithm of a number says a to the base of another number say b is a number say n which when raised as a power of b gives a. (i.e. log [base ...

You may find this hard to believe, but there are people still alive today who once did their mathematical calculations by sliding sticks back and forth. No keypads, no batteries, no LEDs. Just sticks.

Logarithms are a convenient way to express large numbers. Before the invention of calculators, the only alternative to slide rules was to use tables of logarithms. Some important formulae, also called ...

Log tables, invaluable in science, industry and commerce for 350 years, have been consigned to the scrap heap. But logarithms remain at the core of science, as a wide range of physical phenomena ...
