# Mathematical Symbols Page #9

#### This page lists all the various symbols in the Mathematical Symbols category.

This is a list of symbols found within all branches of mathematics.

## Symbols in this category:

### There exists

There is at least one value of x for which f(x) is true.

### There exists exactly one

There is exactly one value of x for which x is true.

### Therefore

Specifies because of a set conditions therefore another condition is true.

### Thrembo

Thrembo is a fictional number, specifically an integer, between six and seven, created and spread on social media as a joke.

### True

This symbol represents the boolean value "true".

### Union

The union of two sets is the set of all objects in both sets.

### Unit Vector

A vector that has a length of 1.

### Universal Quantification

This represents "for all" (or better "for each") or "given any".

### Universal set

The set that contains all possible values.

### 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.

### xor (exclusive or)

The result of A xor B is true if A is True or B is True but not both True.

### Zero

Zero is the number before 1 and after -1. It is used as a place holder in base ten systems.

### ±

More or less

• You left out "+-" That is the symbol for the quantum value of something that is both plus and minus, not just one or the other. It is something that is both true AND false at the same time. It is represented graphically by a frequency that has the y limits of plus 1 to minus 1 through zero. The line goes between those two limits at a frequency that is determined by the situation represented by it. Also, It is the graphic representation of the square root of -1, which is not imaginary in the least.
It is furthermore a depiction of the difference between the sexes with regard to thought. The female travels in logic between -1 and zero, but the male must stay between +1 and any positive value and cannot go to zero and remain a man. This provides the female with a degree of freedom that the male doesn't have. He can see what she is doing only when she comes to the zero line. Then her logic takes her below the line in a place he cannot see logically. When she returns to the zero line, she pops up in a place that he has not seen her logic take her to. Thus, she is considered to be a typical "dizzy blonde." The reason for that term's extistence is that she makes the man dizzy. Her thought process is just as logical as his, but he cannot see it. She can see his, however, so she has a degree of freedom to change her mind without explanation that he doesn't have.
Just thought you ought 'a know, as I am a man and want this idea to take hold in other men's thoughts. There is too much misunderstanding between men and women. In addition, the symbol should be there.
