What's a complex number?
- A.
It's a number that can be expressed in the form of a+bi, where a and b are real numbers.
- B.
It's a number that can be expressed in the form of a+bi, where a is a real number.
- C.
It's a number that can be expressed in the form of a+bi, where b is real number.
- D.
It's a number that can be expressed in the form of a+bi, where a and i are real numbers.
Correct Answer
A. It's a number that can be expressed in the form of a+bi, where a and b are real numbers.Explanation
A complex number is a number that can be expressed in the form of a+bi, where a and b are real numbers. This form includes both a real part (a) and an imaginary part (bi), where i is the imaginary unit. The real part represents the horizontal component of the number on the complex plane, while the imaginary part represents the vertical component. Therefore, a complex number combines both real and imaginary components.Rate this question:

What's the other term for a polynomial ring?
- A.
Polynomial mathematics
- B.
Polynomial algebra
- C.
Polynomial calculation
- D.
Polynomial circle
Correct Answer
B. Polynomial algebraExplanation
The other term for a polynomial ring is "Polynomial algebra." This term is used to describe the study and manipulation of polynomials, which are mathematical expressions consisting of variables and coefficients combined through addition, subtraction, multiplication, and exponentiation. Polynomial algebra involves various operations and techniques for solving equations and analyzing polynomial functions.Rate this question:

What's algebraic geometry?
- A.
It's a branch of mathematics, classically studying zeros of multivariate polynomials
- B.
It's a branch of mathematics, classically studying ones of multivariate polynomials
- C.
It's a branch of mathematics, classically studying threes of multivariate polynomials
- D.
It's a branch of mathematics, classically studying tens of multivariate polynomials
Correct Answer
A. It's a branch of mathematics, classically studying zeros of multivariate polynomialsExplanation
Algebraic geometry is a branch of mathematics that focuses on studying the zeros (also known as solutions or roots) of multivariate polynomials. This field combines techniques from algebra and geometry to understand the geometric properties of these solutions and their relationships. By examining the zeros of polynomials, algebraic geometry provides insights into the structure and behavior of algebraic varieties, which are objects defined by polynomial equations.Rate this question:

What's triangular matrix?
- A.
It's a special kind of cylindre matrix.
- B.
It's a special kind of circle
- C.
It's a special kind of square matrix.
- D.
It's a special kind of shape matrix.
Correct Answer
C. It's a special kind of square matrix.Explanation
A triangular matrix is a special type of square matrix where all the elements either above or below the main diagonal are zero. In other words, all the elements in the matrix either lie on or below the main diagonal (lower triangular matrix) or on or above the main diagonal (upper triangular matrix). This type of matrix has a distinct shape, resembling a triangle, hence the name "triangular matrix".Rate this question:

What's are algebraic varieties?
- A.
They are the central objects of study in algebraic geometry
- B.
They are some of the objects of study in algebraic geometry
- C.
They are the last objects of study in algebraic geometry
- D.
They are the central objects of study in geometry
Correct Answer
A. They are the central objects of study in algebraic geometryExplanation
Algebraic varieties are the central objects of study in algebraic geometry. This field of mathematics focuses on the study of geometric objects defined by polynomial equations. Algebraic varieties are sets of points in affine or projective space that satisfy a system of polynomial equations. They play a fundamental role in algebraic geometry as they provide a way to understand the geometry of these objects through algebraic methods.Rate this question:
