Understanding the Generality of Logic Statements

In summary, the conversation discusses the concept of compound statements using the symbols \leq and the rules for determining their truth values. It also touches on the idea of generality and how it applies to statements involving prime numbers.

Homework Statement



sorry but I'm confused

is it okay if i say [tex]2 \leq 2[/tex] or [tex]1 \leq 2[/tex]

and this example

i know this is true

"if p is prime then p>1"

but is this true?

"if p is prime then p>-20"

its true right? because the generality doesn't change

Yes to both. For the first, [itex]2 \leq 2[/itex] means that either 1) 2 < 2 (false) OR 2) 2 = 2 (true). For a compound statement with OR, the whole statement is true if either or both of the parts are true.

Yes. Primes are considered to be positive integers that are greater than or equal to 2.
