Algebra help!?

Question

Can someone explain algebra to me?

Answer 1

u know its name comes from an iranian mathematician called ALKHARAZMI

Answer 2

A branch of mathematics that substitutes letters for numbers. An algebraic equation represents a scale, what is done on one side of the scale with a number is also done to the other side of the scale. The numbers are the constants. Algebra can include real numbers, complex numbers, matrices, vectors etc. Moving from Arithmetic to Algebra will look something like this: Arithmetic: 3 + 4 = 3 + 4 in Algebra it would look like: x + y = y + x

Answer 3

The answer from Palomino08 is very good but omits one element. Algebra is a method in mathematics by which you can find out the value of something when other related values are known. These usually are expressed as the dreaded "word" problems. If Ginny has 6 pencils and pencils cost $.15 each, how much money did Ginny spend? The "how much" is the unknown. The quantity and cost of pencils is known and all of these are related. Symbols are used to make writing the equation easy. Instead of "how much money did Genny spend = ...", we use "X" for the "how much..." part. So, X = 6 pencils multiplied by the $.15 cost per pencil or: X = 6 * $.15.

Answer 4

well algebra is a certail topic of maths where u dont know a particular value so u use algebra to find it:

for eg: x - 4 =2
or, x = 6

ur only answer to this question is 6 this is how algebra works if u want some specific help then send me : [e-mail]

hope this will help u!

Answer 5

Suppose that for any coherent proposition $ P(x)$, we can construct a set $ \{x: P(x)\}$.


Let $ S = \{x: x \not\in x\}$. Suppose $ S \in S$; then, by definition, $ S \not\in S$. Likewise, if $ S \not\in S$, then by definition $ S \in S$. Therefore, we have a contradiction.


Bertrand Russell gave this paradox as an example of how a purely intuitive set theory can be inconsistent. The regularity axiom, one of the Zermelo-Fraenkel axioms, was devised to avoid this paradox by prohibiting self-swallowing sets.

An interpretation of Russell paradox without any formal language of set theory could be stated like “If the barber shaves all those who do not themselves shave, does he shave himself?”. If you answer himself that is false since he only shaves all those who do not themselves shave. If you answer someone else that is also false because he shaves all those who do not themselves shave and in this case he is part of that set since he does not shave himself. Therefore we have a contradiction.

wrong post hehehe

Answer 6

Algebra is a branch of mathematics concerning the study of structure, relation and quantity. The name is derived from the treatise written by the Persian mathematician Muhammad bin Mūsā al-Khwārizmī titled (in Arabic كتاب الجبر والمقابلة ) Al-Kitab al-Jabr wa-l-Muqabala (meaning "The Compendious Book on Calculation by Completion and Balancing"), which provided symbolic operations for the systematic solution of linear and quadratic equations.

Together with geometry, analysis, combinatorics, and number theory, algebra is one of the main branches of mathematics. Elementary algebra is often part of the curriculum in secondary education and provides an introduction to the basic ideas of algebra, including effects of adding and multiplying numbers, the concept of variables, definition of polynomials, along with factorization and determining their roots.

Algebra is much broader than elementary algebra and can be generalized. In addition to working directly with numbers, algebra covers working with symbols, variables, and set elements. Addition and multiplication are viewed as general operations, and their precise definitions lead to structures such as groups, rings and fields.

Answer 7

Algebra means "the unknown"...
hey have you tried researching?? there are textbooks and brief histories!:c

Answer 8

The whole subject? No, not without becoming a professional tutor, which I cannot do now. Ask specific problems and I will try to help you solve them.

Answer 9

Yes! Like what?

Answer 10

Be specific, what do you want to know?
