When you use deduction and start form a given set of rules and conditions?

When using deduction, you begin with a set of established rules or premises and logically derive conclusions based on those premises. This process involves applying logical reasoning to ensure that the conclusions drawn are valid if the initial conditions are true. Deduction is often used in mathematics and formal logic to prove statements or theorems by demonstrating that they necessarily follow from the given assumptions. Ultimately, it allows for systematic exploration of implications within a defined framework.
