The entry on page 130 reads (approximately): algorithm: Arabic words, which are used to imply the six operations of arithmetic, or the science of numbers.

Today, "algorithm" is defined as:

- A well-defined procedure to solve a problem.

- A clearly specified set of simple instructions to be followed to solve a problem.

- A finite, deterministic, and effective problem-solving method.

- An explicit, precise, unambiguous, mechanically-executable sequence of elementary instructions.

^{1}

- A sequence of computational steps that transform input into output.

^{2}

- A set of rules that precisely defines a sequence of operations.

^{3}

- A precisely defined set of mathematical or logical operations for the performance of a particular task.
