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.

Adaptation is the result of natural selection.
by natural selection.
Yes, natural selection is always occurring.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.

Adaptation does not allow for natural selection: natural selection causes adaptation.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Natural selection is what causes adaptation.
No, natural selection is the mechanism that drivesevolution.
Adaptation is the result of natural selection.

No, natural selection is believed to result in evolution.
