What is the difference between universal and conditional statement?

What is the difference between universal and conditional statement?

An existential statement is a statement of the form ”∃x ∈ D such that Q(x).” It is defined to be true if, and only if, Q(x) is true for at least one x in D. A universal conditional statement has the form: ∀x, if P(x) then Q(x). For Example: Rewrite each of the following statements in the form: ∀ , if then .

How do you prove a universal statement?

Following the general rule for universal statements, we write a proof as follows:

1. Let be any fixed number in .
2. There are two cases: does not hold, or. holds.
3. In the case where. does not hold, the implication trivially holds.
4. In the case where holds, we will now prove . Typically, some algebra here to show that .
