## Why is it called Dressed to the nines?

Why it should have been to the nines rather than to the eights, to the sevens, etc.

## What does and mean in logic?

In logic, mathematics and linguistics, And (∧) is the truth-functional operator of logical conjunction; the and of a set of operands is true if and only if all of its operands are true. The logical connective that represents this operator is typically written as ∧ or ⋅ .

## What does watch your six mean?

“Got your six” Meaning: Watching your back. Military members commonly describe direction using the hours of a clock. Whichever direction the vehicle, unit, or individual is moving is the 12 o’clock position, so the six o’clock position is to the rear.

## What does or mean in logic?

In logic and mathematics, or is the truth-functional operator of (inclusive) disjunction, also known as alternation; the or of a set of operands is true if and only if one or more of its operands is true. The logical connective that represents this operator is typically written as ∨ or +.

## What does P stand for in algebra?

In probability and statistics P(X) means the probability of X occurring. In set theory, P(X) means the power set of X. In geometry, P can refer to a projective space although it is also often the name given to a partic.

## What is the Contrapositive of P → Q?

Contrapositive: The contrapositive of a conditional statement of the form “If p then q” is “If ~q then ~p”. Symbolically, the contrapositive of p q is ~q ~p.

## What does P mean in logic?

Laurie Schroeder Date: 11/29/2001 at 10:09:24 From: Doctor Tom Subject: Re: Logic Hi Laurie, “p” stands for “proposition” — a statement that’s either true or false. Then when you talk about a second proposition, people just tend to use nearby letters.

## Is fubar a military term?

A number of military slang terms are acronyms. Rick Atkinson ascribes the origin of SNAFU (Situation Normal, All Fucked Up), FUBAR (Fucked Up Beyond Any Repair or “All Recognition”), and a bevy of other terms to cynical GIs ridiculing the United States Army’s penchant for acronyms.

## When p is false and q is true then p or q is?

A tautology is a statement that is always true. A contradiction is a statement that is always false. DeMorgan’s Laws. If p and q are propositions, the conditional “if p then q” (or “p only if q” or “q if p), denoted by p → q, is false when p is true and q is false; otherwise it is true.

## What does P and Q stand for?

Another proposed origin is from the English pubs and taverns of the 17th century. Bartenders would keep a watch on the alcohol consumption of the patrons; keeping an eye on the pints and quarts that were consumed. As a reminder to the patrons, the bartender would recommend they “mind their Ps and Qs”.

## What is the truth value of P ∨ Q?

Disjunction Let p and q be propositions. The disjunction of p and q, denoted by p ∨ q, is the proposition “p or q.” The truth value of p ∨ q is false if both p and q are false.

## What does Q stand for in geometry?

rational numbersList of Mathematical Symbols. • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.

## What do P and Q stand for in math?

The statement “p implies q” means that if p is true, then q must also be true. The statement “p implies q” is also written “if p then q” or sometimes “q if p.” Statement p is called the premise of the implication and q is called the conclusion.

## Why do they say I got your six?

What is “Got Your 6”? … In the military, “Got your six” means “I’ve got your back.” The saying originated with World War I fighter pilots referencing a pilot’s rear as the six o’clock position. It is now a ubiquitous term in the military that highlights the loyalty and cooperation found in military culture.

## What is logically equivalent to P and Q?

A compound proposition that is always True is called a tautology. Two propositions p and q are logically equivalent if their truth tables are the same. Namely, p and q are logically equivalent if p ↔ q is a tautology.
