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.

Plain what? If you're referring to U.S. coins there were 5 denominations struck that year so more information is needed. The best thing to do is to post a new question with the coin's denomination and condition.
What is an inverese in algebra?
An inverse is another word for opposite. The inverse for adding is subtraction, multiplication is division, etc. If you are solving an equation, and have to get a variable alone, you must eliminate any other numbers with the variable, which means undoing the operation (x, +, -, /); so you perform the inverse.
Example:
x + 3 = 9.
Subtract 3 on both sides to get x alone, because subtraction is the inverse of addition:
x = 6.
Example:
2x + 3 = 9.
You must do the inverse of addition and subtraction before the inverse of multiplication and division. In this case, after subtracting 3 you have:
2x = 6.
x is being multiplied by 2, so the inverse is division, and your answer is x = 3.
What is the value of a 5.00 1893 gold coin1?
It depends on the mint mark and condition. See http://www.numismedia.com/fmv/prices/5gld/pricesgd.shtml for one site that shows a list of values.
What is the factor of 2x²-12x plus 11?
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions:
3 plus or minus 0.5 times the square root of 14
x = 4.87082869338697
x = 1.1291713066130293
What does the R in missouri's R-IV schools mean?
The "R" in Missouri's R-IV schools designates the school district's classification, where "R" stands for "Rural." The "IV" indicates the district's specific classification level based on student enrollment numbers, with "IV" representing a certain range of students. This system helps categorize and manage school districts throughout the state based on their size and location.
What is the value of a 1951 quarter?
The value of a 1951 quarter will value depending on the condition and where it was minted. The value ranges from 3.52 to 4.30.
22 matrix with 33 matrix multiplication?
It is not possible. The number of columns in the first matrix must be the same as the number of rows in the second.
That is, matrices, X (kxl) and Y (mxn) can only be multiplied [in that order] if l = m.
Difference between subset and proper subset?
A subset of a set S can be S itself. A proper subset cannot.
Abū ʿAbdallāh Muḥammad ibn Mūsā al-Khwārizmī created is believed to be the father of algebra (called algebra because the Arabic word al-jabr was used in the title of his book, which means "stress" or "something to stress over")
Is empty set an improper subset?
Recall that Improper subset of A is the set that contains all and only elements of A. Namely A.
So does the empty set have all of A provided A is not empty? Of course not!
The empty set can be only considered an improper subset of itself.
How many combination 0to9 digits select 4digits?
0000 to 9999
So answer is 10,000
as 0001 to 9,999 is 9,999
plus 0000 is a number also
so 9,999 + 1 = 10,000
How do you draw the number line representing the following numbers like whole numbers 65?
65 is a whole number!
How do you solve the system by graphing -5x-y equals -2 x-3y equals 10?
Where the lines intersect that gives the values for x and y in the two equations.
The lines should intersect at (1, -3) because x = 1 and y = -3
