1. irrational number. The square root of two does not terminate, and it does not repeat a pattern. It cannot be written as a quotient of two integers, so it is irrational. 3. The Associative Properties state that the sum or product of multiple numbers can be grouped differently without affecting the result.

A ...Then P(n) is true for all natural numbers n. For example, we can prove by induction that all positive integers of the form 2n − 1 are odd. Let P(n) represent " 2n − 1 is odd": (i) For n = 1, 2n − 1 = 2 (1) − 1 = 1, and 1 is odd, since it leaves a remainder of 1 when divided by 2. Thus P(1) is true.First-order logic—also known as predicate logic, quantificational logic, and first-order predicate calculus—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science.First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables, so that rather …1. 3x 5 = 17 = 4 2. r 3.5 = 8.7 r = 12.2 3. 4t 7 = 8t + 3 t = – 5 2 n = –38 5. 2(y – 5) – 20 = 0 Agenda: Warm-Up/Pull SG Algebraic Proofs Notes Practice Proofs y = 15 Essential Questions How do we identify and use the properties of equality to write algebraic proofs?

In this section, we will list the most basic equivalences and implications of logic. Most of the equivalences listed in Table \(\PageIndex{2}\) should be obvious to the reader. Remember, 0 stands for contradiction, 1 for tautology. Many logical laws are similar to algebraic laws.Writing Algebraic Proofs • Algebraic proofs involve solving a multi-step linear equation, showing and justifying each step that you take • To write an algebraic proof: • Go step by step • Write your steps in a column called “statements” • You must give a reason for every step • Write your reasons in a column called “reasons” Let \(S\) be the set of all integers that are multiples of 6, and let \(T\) be the set of all even integers. Then \(S\) is a subset of \(T\). In Preview Activity \(\PageIndex{1}\), we worked on a know-show table for this proposition.
