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.

What are two ways to classify minerals?
Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.
What is irratoinal numbers?
An irrational number can not be expressed as a fraction such as the square root of 2
Can every prime number be expressed as the product of 2 prime numbers?
No, none can.
Difference between rational and irrational?
Rational numbers can be expressed in the form p/q (where q is not equal to zero). Irrational numbers cannot be expressed in this form. For example, the square root of 2 cannot be expressed as p/q.
