Please hand me the marker labeled number 2.

In infrared spectroscopy, the intensity of an absorption peak often depends on the wave number assigned to a vibrational mode.

When preparing the report, please format the section headings as a numbered list that uses both Arabic numerals (1, 2, 3) and Roman numerals (I, II, III) to indicate different levels.

When I looked up at the night sky, the numberlessness of the stars overwhelmed me with a sense of awe.

In linguistics class, the professor explained how a distributive number like 'two each' functions differently from a cardinal numeral.

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.
