Cullen numbers often appear in discussions of primality tests because of their distinctive form.

Algebraists often compare ideal numbers across different rings to understand factorization properties.

A hyperbolic number can be expressed as x + yj with j^2 = 1, and it provides a convenient algebraic framework for two-dimensional Lorentzian geometry.

In the lecture, the professor compared hyperbolic numbers to complex numbers to highlight their distinct algebraic properties.

In algebraic number theory, each invertible ideal can be represented by an ideal number in the ring of integers of a number field.

Journalists published the leaked report, which listed apocalyptic numbers for food shortages that shocked the nation.

Scholars debated whether the apocalyptic number carved into the ancient manuscript referred to 666 or was a later interpolation.

Graduate students studied the algebraic properties of tricomplex numbers during the advanced complex analysis seminar.

When the Knudsen number exceeds about 0.1, gas flow through the aperture transitions into a rarefied regime where molecular collisions with the walls dominate.

When plotting data, remember that positive numbers are shown to the right of zero.
