Abstract Algebra
Have you ever wondered what would happen if you redefined some of the basic rules of algebra so that concepts you took for granted, like AB = BA, no longer apply? Abstract algebra does just that through the study of the properties that define algebraic structures. Post all questions about fields, rings, group theory, vector spaces, and the axioms that define them into this category.

What is the value of a 1936 beer can?
There were numerous breweries producing beer cans starting in 1934. The earliest cans were flat tops that required a can opener and had opening instructions on the side panel. Beginning in 1935 a cone top beer can design was also produced. Any can made during the 1930's will have the term Internal Revenue Tax Paidsomewhere on the can.
Overall there were 1000's of different beer cans being produced by 1936. The value of any such can will range from $50 to $5000+ depending on the actual can and the condition. The condition is very important and minor flaws affect the value significantly.
I've been collecting U.S. beer cans and breweriana for almost 30 years. If you wish to learn more about old beer cans, see the link, further down this page, listed under "Related Links."
The value of the1896 Krag-Jorgensen rifle is dependent on it's condition.
Sound wood
Clear cartouches
% of bluing
Markings and serial number
Matching serial numbers on receiver and bolt
All original parts unaltered
If the rifle is in Excellent condition and looks new, it could be worth as much as $5,000. If it is a little shop worn with only half of its original bluing its worth would be closer to $700.

What is the value of a JCHiggins 20gauge model 583.22?
The Blue Book of Gun Values says that all of the JC Higgins (Sears brand) guns have no collector value, only shooter value. Also, the 583.22 is one of the ones that was recalled by Sears.
What is the average of 40MPH by 5 MPH?
You cannot average speeds without knowing how much time is spent traveling at each speed
a = time at 40, b= time at 5
Ave Speed = (40a +5b)/(a + b)
What is the value of a 1903 british rifle 303?
The value of any firearm is based on exact make/model, condition, and orginality. A SMLE from 1903 in good/ very good condition may bring $150-$250. Rifles that have been "sporterized" are worth far less.
How do you prove Schur's lemma?
CK(J) = {x Є K: jx = xj for all j Є J}.
Also, using the established theorem that "if J is a subset of ring K, then C(J) is a subring of K, and if an invertible element a of K belongs to C(J), then k-1 Є C(J)," we need only show that if g Є C* (C* being the set of non-zero elements of C), then g is an automorphism of E. Assuming non-triviality, g � 0, and there exists
b Є E such that g(b) � 0. For each h Є E there exists m Є K such that m(g(b)) = y since K is primitive. Thus: g(m(b)) = m(g(b)) = y, showing that g is surjective.
Finally to show g is also injective and thus an automorphism, we take a non-zero element w belonging to the kernel of g. For each z Є E some endomorphism would exist u Є K such that u(w) = z as K is primitive. Therefore:
g(z) = g(u(w)) = u(g(w)) = u(0) = 0, the zero endomorphism which is a contradiction. Hence g is injective and an automorphism of E.

How high on a wall does a 12-ft ladder reach when the base of the ladder is 3 ft fr?
Use Pythagoras' theorem: 122-32 = 135 and its square root gives the answer of 11.619 feet rounded to 3 decimal places

What kinds of sets are there in algebra?
There are all kinds of sets in algebra. And that may not help, but it's true. There is a whole branch of algerbra that deals with the (algebraic) manipulation of sets. And don't even think about going to look at set theory. There are several branches of that, and it may well just add confusion. Sets, which are, in general, groups of "things" that are considered and manipulated as a "whole thing" by rules of mathematics, can vary in number. Just as an infinite number of things can be considered to be part of a set, there are many, many different kinds of things that can be put into a set.
How about a "regular" set of table flatware? Subsets would be knives, salad forks, dinner forks, soup spoons and teaspoons. (Leave out all the "fancy" stuff.) How about a set of the stuff that goes on the right side of the plate in a "regular" setting as a subset of flatware? That'd be the knife and spoons. See how this works? It could take you all day to make sets of the things in your house. And the sets could be anything! Things made completely of metal, completely of wood, completely of glass (excluding ceramics). Things normally found in the kitchen could be a set, or it could be a subset of the stuff in your house. We could go on and on.
In number theory, there are some interesting problems of sets, but, again, sets can be as varied as the imagination of the person dreaming them up....
Kinds of set:
*infinite set:
-the set continues on for infinity.There may not be an infinite amount of a thing you wear, it is limited to numbers.
*finite set:
-it has finite (countable) number of elements, it has unlimited numbers.
*numerical set:
-a set having only numbers as its elements, set prime numbers (2,3,5,7,11,13,17..)
*equal set:
-two sets are equal if they have precisely the same numbers.
*null set:
-its is a set with no elements or numbers.
*equivalent set:
-sets with the same numbers of members .
*intersecting sets:
-sets with some members in common.
*subsets:
-sets contained within others are subset.
Who are the pioneers of algebra?
The person who developed algebra was famous Muslim mathematician Al-Khawarizmi. He is know as the "father" of algebra, and lived during the Golden Age of Islamic civilization during the Abbasid Dynasty.

What is the traditional method of computing square root?
you need to factor it say it is x^2-4 you would factor it by doing (x+2)(x-2) and then you simplify if needed
What is the value of a 1890 zimmerman autoharp?
I own an 1899 Zimmerman autoharp. Unfortunately these wonderful instruments have not been recognized for their true worth. They are "the original autoharps" and should be worth much more than they are. If they were guitars of similar quality and historical value (ie. a Martin New Yorker) they would be worth many thousands of dollars. Mine, which is in very fine condition is worth $80-$100 dollars. Be assured, however, one day they will be discovered and there value will shoot through the roof. Right now be pleased by the fact that you own a very important piece of American musical history...
Is the symmetry group of the square an abelian group?
Abelian meaning commutative. If the symmetry group of a square is commutative then it's an abelian group or else it's not.
Rules of parameterarea in math for 7th class?
Do you mean "perimeter" and "Area"? If so, if you are finding the perimeter of a figure, you take the lengths of all of the sides and add them up. If you are finding area, the method of which you find the area of the figure depends on what the figure is. For quadrilaterals, the formula is: A=lw.(Area=length times width) For triangles, the formula is: A=1/2lw. (Area=One half length times width)
