Logic Symbols
This page lists of the various symbols in the Logic Symbols group.
In logic, a set of symbols is commonly used to express logical representation. As logicians are familiar with these symbols, they are not explained each time they are used. So, for students of logic, the following table lists many common symbols together with their name, pronunciation and related field of mathematics. Additionally, the third column contains an informal definition, and the fourth column gives a short example.
Be aware that, outside of logic, different symbols have the same meaning, and the same symbol has, depending on the context, different meanings.
Symbols in this group:
and
The statement A & B is true if both A is true and B is true. Otherwise the statement is false.
Equivalence
Equivalence is being equivalent or interchangeable. The relationship indicates that both sides are either both true or both false.
Join \ Bowtie
The Join/bowtie is commonly used in logic math and seen as philosophically symbolic.
Logical Implication (Implies)
The statement on the left side of the symbol implies the statement on the right side. Can also be read as If, Then, i.e., if "statement on left side", then "statement on right side".
MORE OPERATION IN MATHEMATICS
Math operation first number added to summation of itself times base counted down for each digit place until the ones column 10^0.
set equal to
Define the value of a variable as equal to constant or to value of another variable.
Universal Quantification
This represents "for all" (or better "for each") or "given any".
Vertical Bar
The vertical bar (|) is a character with various uses in mathematics, computing, and typography. It may be called by various other names including the polon, pipe (by the Unix community, referring to the I/O pipeline construct), Sheffer stroke (by computer or mathematical logicians), verti-bar, vbar, stick, vertical line, straight vertical line, vertical slash, or bar, glidus, think colon, poley, or divider line.
