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 browning 25 serial number 410882?

My information shows this pistol to be made in 1967. Assuming that it is in good to very good condition, that is, no major scars or scratches, bright bore, no chips or cracks in the grips, a guideline would be 300-375. But keep in mind that gun prices wary widely with the time of year, the area of the country and above all Condition! An original box and/or papers would add some value. The real value is what someone would be willing to pay you.

What is the value of a 1976 TVR 2500 with 36000 miles?

Is the car original or has it been modified in any way? These cars tend to have the original motor pulled in favor of a v8. I have a 73 2500M with 20,000 original miles and I think these cars are undervalued for what they are...a low production, hand built British sports car. Only 947 were made from 1972-1977, so I feel now is the time to buy as these cars will appreciate in the next several years. One thing to be concerned about is corroison on the chassis. If the car is in very good condition, well cared for and not requiring extensive repair the value would be $12,000-$15,000

If skater's time is 1.51.28 in 1000 meters how fast are they going?

If 1.51.28 represents 1 minute 51.25 seconds, then the time taken is approx 1.8547 seconds.

So the speed is 1000/1.8547 = 539 metres/sec, approx.

How do you solve 5xy plus 7xsquared - 12y when x equals 2 y equals 1?

In the given expression you replace x by 2 and y by 1.

Thus 5xy + 7x2 - 12y = 5*x*y + 7*x2 - 12*y

= 5*2*1 + 7*22 - 12*1 = 10 + 28 - 12 = 26

Was anybody involved in the Boolean algebra?

George Boole, the creator of Boolean Algebra, the creators of computers, and all of us that have even once used computers; computers use Boolean Algebra for truth values, making logic circuits.

How do you do middleschool algabra?

-- A good start might be to glance at the cover of your textbook and learn

to spell the subject . . . Algebra .

Then . . .

-- Go to every algebra class, get there on time, turn off your cellphone, stay awake,

and listen to everything the teacher is talking about.

-- At the end of class, write down the homework assignment.

-- At home, do the whole assignment, on time. If there's anything you don't understand,

then either get someone who knows Algebra to help you understand it, or make an

appointment to meet with the teacher for help. Do it right away ! Each part of Algebra

builds on the part before it. If there's something you don't understand and you blow it

off, then there's nothing to build on, and that's the end of Algebra for you, right there.
