This is a variation of the quadratic formula. Similar procedures appear as far back as Babylonia, and represented the state of algebra (and its close ties to astronomy) for more than 3,500 years, across many civilizations: Assyrians, in the 10th century B.C.; Chaldeans, in the seventh ...
The letters x and y represent the areas of the fields. The first equation is understood simply as 'adding the two areas gives a total area of 1,800 square yards.' The second equation is more subtle. Since x is the area of the first field, and the first field had a yield of two-t...
What is classical algebra? The History of Algebra: Mathematics involves studying several different subjects and concepts. Because of this, we have different branches of mathematics, and we can further classify those branches based on specific topics within each branch. Algebra is one branch that has...
which are integers that can't be factored any further. For example, 3 is a prime number, because you can't factor it, but 81 can be written as 3 • 3 • 3 • 3. In addition, there is only one way to factor a given number into its component prime numbers. This ...
rules for manipulating these symbols. It provides a powerful framework for solving complex problems and understanding the relationships between numbers and variables. Whether you are a student or a professional in a technical field, algebra is an essential tool that will serve you well in your ...
In algebra, "log" is short for "logarithm." Logarithms are the opposites, or inverses, of equations involving exponents, like y = x^3. In their simplest form, logs help to determine how many of one number must be multiplied to obtain another number. Logarithms were initially invented to ...
We will show that the set of all\nfree bases of a free group $F$ is 0-definable in the group algebra $K(F)$ when\n$K$ is an infinite field, the set of geodesics is definable, and many geometric\nproperties of $F$ are definable in $K(F)$. Therefore $K(F)$ knows some ...

What exactly is a sigma-algebra? In mathematical analysis and in probability theory, a σ-algebra (also σ-field) on a set X isa collection.of subsets of X that includes X itself, is closed under complement, and is closed under countable unions. ...
Inductance is theresistancethat occurs when a component such as an inductor generates an electromagnetic field that impedes the current. Inductance is measured in henry (H) and symbolized with L. Capacitance, meanwhile, is resistance that occurs when a device such as acapacitorstores an electric ch...
