What year was algebra introduced?
Early Greeks, such as Pythagoras and Euclid, relied on geometry to express all of their logical proofs. It was about 250 CE when the Greek Diophantus (from Alexandria) began using Greek letters as numbers and other mathematical symbols. He is sometimes called the father of algebra. Since this was not developed into a fully symbolic algebra on its own, it is called syncopated algebra.Later, about 820 CE, the Muslims founded the House of Wisdom, a collection of many would-be lost Greek and Indian writings. Here, Al-Khwarizmi wrote Hisab al-jabr w'al-muqabala (Calculation by Restoration and Reduction). The word algebra comes from al-jabr. This algebra was still written out in story problems, but it was the great step away from depending on geometry for proofs.Finally, algebra began to take on its modern symbolic look when Viéte used letters for variables around 1600. Then in 1637, Descartes wrote La géométrie. Before this, mathematicians had thought of polynomials spaically, so x3 actually represented a cube. His written algebra is the first to look almost exactly like ours. (Supposedly, upon printing, Descartes was asked if it mattered which letters were used for variables. He said no, resulting in x,y, and z since they were used least!)
How many times can you subtract 10 from the number 100?
As many times as you feel like it before you get bored and stop. After 10 times, you will be left with zero, and you'll begin going into negative numbers. Bu that should be no problem for you. I thought that it would be only once because then you are subtracting from the number 90 not 100.
Examples of real numbers?
Most numbers are real numbers, but they are called that to distinguish them from imaginary ones. The best example of an imaginery number is the square root of minus 1. This is not a possibility.
Where did Algebra come from?
Abu Abdullah Mohammad Ibn Musa al-Khawarizmi. Abu Abdullah Mohammad Ibn Musa al-Khawarizmi was born at Khawarizm (Kheva), south of Aral sea. Very little is known about his early life, except for the fact that his parents had migrated to a place south of Baghdad. The exact dates of his birth and death are also not known, but it is established that he flourished under Al- Mamun at Baghdad through 813-833 and probably died around 840 C.E. Khawarizmi was a mathematician, astronomer and geographer. He was perhaps one of the greatest mathematicians who ever lived, as, in fact, he was the founder of several branches and basic concepts of mathematics. In the words of Phillip Hitti, he influenced mathematical thought to a greater extent than any other medieval writer. His work on algebra was outstanding, as he not only initiated the subject in a systematic form but he also developed it to the extent of giving analytical solutions of linear and quadratic equations, which established him as the founder of Algebra.
What are examples of irrational numbers?
An example is the square root of a number. Ex: square root of 2. This is 1 example, not the main one. Any cube root or square root which doesn't give a perfect number is an irrational number. Ex; square root and cube root of 5, since their answer will be 2.24 and 1.70 which are not perfect numbers like square roots of 25 and 64 or cube roots of 27 and 216.
Where do you find pre-algebra with pizzazz answers?
Technically unless you are a teacher you cant! but why don't you just go and ask your pre algebra teacher or parent for help? that's always a thought.
What do you do about liking a teacher?
nothing...i thought my algebra teacher was smokin hot when i was in highschool but i promise you, the teacher will not be attracted to a student...at least not in highschool or middle school
What is the definition of negative numbers?
A negative number is any real number that is less than zero. Such numbers are often used to represent the amount of a loss or absence. For example, a debt that is owed may be thought of as a negative asset, or a decrease in some quantity may be thought of as a negative increase. Negative numbers are also used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
Why is Muhammad ibn musa al-khwarizmi called father of algebra?
he was often thought of as the father of algebra because he was the first to teach algebra in such an elementary way.
What 2 numbers add to 400 and multiply to 960000?
-1200 and -800, I thought at first, but I cannot think of 2 numbers possible. if 1200 is positive, 960000 has to be negative
What is the answer to 7.11 in the punchline algebra book?

How is algebra used in designing?
Its like my geometry teacher said, "You probably won't ever need to know everything I am going to teach you but you will need to know the tactics and thought process and solving skills you will learn by doing these problems."
What is the definition of set in college algebra?
All of mathematics can be defined in terms of sets. Sets are used to give an axiomatic definition of numbers and relations. However, most, if not all of college algebra was known before anybody thought about sets. You have to learn what your teachers expects you to learn, but very little set theory is actually needed for college algebra.
Why is -1 the greatest negative integer?
There are no whole negative numbers greater than -1. Therefore, -1 is the highest negative whole integer. It can be thought of this way: When positive integers get larger, an amount is greater, but when negative integers get larger, the amount is less, so -1 is the greatest negative integer.
What is René Descartes' contribution to algebra?
Rene Descartes initiated the process in which algebra is thought upon. His major contribution was making me have to do this pointless essay.
Why is algebra helpful?
Algebra can help us to use abtract thought in the form of mathematical solutions to resolve common everyday problems. Mb
How is an english double negative like subtracting negative number?
subtraction is merely adding a negative number, so subtracting a negative number is adding the negative of a negative number. It should be pointed out that while most people find this concept obvious, it was not obvious to ancient mathematicians. In fact, as late as the 1800s, most mathematicians thought that negative numbers were nonsense.
