In mathematics and mathematical logic, Boolean algebra is a branch of algebra.It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers.
Every polynomial in one variable x with real coefficients can be uniquely written as the product of a constant, polynomials of the form x + a with a real, and polynomials of the form x 2 + ax + b with a and b real and a 2 − 4b < 0 (which is the same thing as saying that the polynomial x 2 + ax + b has no real roots).
Stalag VIII-A was a German World War II prisoner-of-war camp, located just to the south of the town of Görlitz in Lower Silesia, east of the River Neisse. The location of the camp lies in today's Polish town of Zgorzelec , which lies over the river from Görlitz.
