hardness
The crystallographic axes of minerals are expressed as numbers. As such these numbers can also be used to describe the orientation of mineral cleavage planes. The Mohs hardness, specific gravity, and melting point of minerals are also properties that can be expressed numerically.
Physical properties that can be expressed in numbers include mass, volume, length, temperature, density, pressure, and energy. These properties can be quantified using different units of measurement, such as kilograms, meters, degrees Celsius, etc.
The physical properties of minerals are determined by their chemical composition and atomic structure.
The following minerals have magnetic properties: Magnetite and hematite are ferromagnets. Ferrites and garnets are ferrimagnetic. Quartz, calcite, and mica are all magnetic. Although they have a small magnetic attraction, these minerals do not remain magnetic.
Some special properties of minerals that apply to only a few include fluorescence (ability to emit light when exposed to ultraviolet light), pleochroism (displaying different colors when viewed from different angles), and iridescence (displaying rainbow-like colors). These unique properties can help in identifying specific minerals.
The crystallographic axes of minerals are expressed as numbers. As such these numbers can also be used to describe the orientation of mineral cleavage planes. The Mohs hardness, specific gravity, and melting point of minerals are also properties that can be expressed numerically.
Two properties of minerals that can be expressed in numbers are hardness and specific gravity. Hardness is usually determined using the Mohs scale and is expressed as a number between 1 (softest) and 10 (hardest). Specific gravity is the ratio of a mineral's density compared to the density of water and is expressed as a number.
Density, boiling point, melting point, concentration etc...

Density and Specific Gravity The specific gravity (SG) is calculated from weight in air divided by loss of weight in water, expressed in units of grams per cubic centimetre. The specific gravity of most minerals ranges from 1.5 up to 19.5. (CHANNEL FAIZAN BHAI GHAZI)
I'm not sure but I belive that it is hardness
Barber numbers are integers that cannot be expressed as the sum of distinct divisors of themselves. They have interesting properties in number theory and are used in cryptography for generating secure keys.
They are the properties that are unique to certain minerals such as flourescence or radioactivity
All numbers can be expressed using exponents.
Rational numbers can be expressed as fractions whereas irrational numbers can not be expressed as fractions.
