There is no single mathematical formula for all of natural selection. Although, if you're interested in mathematical descriptions of natural selection, I can recommend you read a few books on population genetics, such as Principles of Population Genetics, by Hartl and Clark.
Natural selection occurs when:
- There exists a population of organisms that reproduce with variation.
- Variant features are inherited by offspring.
- The population produces more offspring than can comfortably subsist within its direct environment.
- Variant offspring therefore have to compete with one another for resources and mating opportunities.
Simply put: the traits of those variants that are better at producing offspring will have a greater frequency in future generations.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
No, natural selection works on that genetic variation presented to it.

Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Natural selection is what causes adaptation.
