Mathematicians
Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

Was there only one Pythagoras or where there a group of people called the Pythagoreans?
Both. There was a man named Pythagoras and his followers were called the Pythagoreans. Yes, there was someone called Pythagoras, and those loyal to him were Pythagoreans, though Pythagoreans sounds more like a tribe of natives than a bunch of people who followed a man.
Who was the first person to discover algebra?
The word algebra is a Latin variant of the Arabic word al-jabr. This came from the title of a book, "Hidab al-jabr wal-muqubala", written in Baghdad about 825 A.D. by the Arab mathematician Mohammed ibn-Musa al-Khowarizmi.
The words jabr (JAH-ber) and muqubalah(moo-KAH-ba-lah) were used by al-Khowarizmi to designate two basic operations in solving equations. Jabr was to transpose subtracted terms to the other side of the equation. Muqubalah was to cancel like terms on opposite sides of the equation. In fact, the title has been translated to mean "science of restoration (or reunion) and opposition" or "science of transposition and cancellation" and "The Book of Completion and Cancellation" or "The Book of Restoration and Balancing."
Jabr is used in the step where x - 2 = 12 becomes x = 14. The left-side of the first equation, where x is lessened by 2, is "restored" or "completed" back to x in the second equation.
Muqabalah takes us from x + y = y + 7 to x = 7 by "cancelling" or "balancing" the two sides of the equation.
Eventually the muqabalah was left behind, and this type of math became known as algebra in many languages.
However, algebra was not invented by any single person or civilization. It is a reasoning skill that is most likely as old as human beings. The concept of algebra began as a reasoning skill to determine unknown quantities.
For example, an early human being (living nearly 7 million years ago) probably ran across the problem of food being stolen from him by other animals... He may have had 5 berries laying on the ground, but then, suddenly a bird flew by and now only had 2. He probably wondered how many berries the bird ate (an unknown quantity). He could probably reason that 3 berries were missing and thus 3 berries were eaten by the bird.
If you perceive algebra in this way, then no one invented algebra because it is a natural instinct encoded in our genetics... it is our ability to reason out quantities that produce algebra. However, the elaboration of this reasoning into structured symbolization and manipulation is not credited to any single individual. Many people, throughout the world and throughout the ages, have developed parts of what is now known as ALGEBRA. The word itself -algebra- comes from a book called Kitab al-Jabr wa-l Muqabala (translated: Calculation by Way of Restoration and Confrontation or Calculation by Completion and Balance), written by Persian mathematician Muhammad ibn Mosa al-Khwarizmi (approximately) in the year 820 AD. However, this was not the first written record of algebraic concepts or manipulation. Ancient Egyptians, Babylonians, Indians, Chinese, and Greeks all have written records of algebra dating far before this date. No one can specify any one time, place, or person solely responsible for the elaboration of algebra as a mathematical discipline.
However, it is true that the Acient Greeks invented "algebraic method" in which you solve a problem by calling a unknown in the question x, then list out all the other expressions containing x. Then you find two equal expressions and form a equation and solve it.
How Do You Find Integer On Math Problems?
An integer is any whole number. It could be positive, zero or negative.
What are some Italian contributions to mathematics?
Google: Peano, Fibonacci edit: The above are contributors, not contributions so it does not answer the question. Italian geometry of about a century ago was the start of what is considered "modern geometry." Italy is still a strong contributor to geometry as well as to practically all fields of mathematics.
How much gas left when warning light?
You typically have 30 miles of driving available, depending upon your gas mileage.
The 2002 odyssey has about 4.5 gallons left when the light goes on. I have gone 75 miles with it on before refueling.
Conon (c. 280--220 B.C.) and Eratosthenes (c.276--194 B.C.)
I am pretty sure it is: 'Leonardo de Pisa', or Leonardo Pisano in italian... the only reason he is called Fibonacci is because his fathers name is Bonacci, and Fi is used as a pre-title. Fi mean son. kind of like John-son, or Robin-son... hope this helps.
Is this a number how do you say it 1234567890987654321234567890987654321234567890987654321?
Yes it is a number. It is on the order of 1.2 x 1055, which would start out as follows: 12 septendecillion 345 sexdecillion 678 quindecillion 909 quattuordecillion... See the related link for naming large numbers.
How do holographic images work?
Holography is a method of photography where 3D objects are recorded by using a laser , then restored to match to the originally recorded object as best they can. what makes thee picture look like it's moving is just created by a source of light.
Did Archimedes have any awards?
In 2007 Archimedes Geo3D was awarded with a "digita". This is an award for outstanding educational software by the German government.

"She will be the woman dressed in sequins."
