Arabic numerals are the ten digit symbols from 0 to 9 that we commonly use. Although called 'Arabic' numerals, they were actually invented by ancient Indians and later transmitted to Europe by Arabs, which is how they got this name. They are the number notation used worldwide today.

Algebra is a fundamental branch of math that mainly studies using symbols (like letters) to represent numbers for operations, reasoning, and analyzing numerical relationships. In English, it's called Algebra. It's more than just arithmetic; it's about finding general ways to solve problems through abstract symbols.
An arithmetic sequence is a sequence where, starting from the second term, the difference between each term and the previous one is the same constant. This fixed difference is called the common difference, usually represented by the letter d. For example, the common odd number sequence 1, 3, 5, 7... has a difference of 2 between each pair of consecutive numbers, which makes it an arithmetic sequence with a common difference of 2.
The angles in a polygon mainly include two key concepts: interior angles and exterior angles.
Azimuth is the horizontal angle measured clockwise from the north direction at a point to the target direction, ranging from 0° to 360°.
Analyzing data usually refers to using statistical methods to organize, study, and summarize a large amount of collected data, extracting useful information and forming conclusions to help with business or operational decisions. In English, it's commonly called Data Analysis or Analyze Data.
An arc usually refers to a geometric shape, formed by a chord and a curve, and its area is calculated by adding and subtracting sectors and triangles.
Aviation refers to the activity of flying aircraft within Earth's atmosphere. Things like the airplanes and helicopters we ride fall into this category, mainly using aerodynamics to lift off, which is different from going into outer space.
Addition is a basic operation in arithmetic, referring to the process of combining two or more numbers or amounts, represented by the plus sign '+', with the result shown using the equals sign '=', and it follows basic properties like the commutative and associative laws.
Architecture usually refers to the general term for buildings and structures, and it’s the man-made environment created by humans using technology.
"Arrow" is a concept with multiple meanings, basically referring to a symbol or object tip that points somewhere; the exact meaning depends on the context.
A figure made up of two rays with a common endpoint is called an angle. This common endpoint is called the vertex of the angle, and the two rays are called the sides of the angle.
In math, associativity is when a binary operation on three or more elements gives the same result no matter how you group them (i.e., where the parentheses are placed).
Aesthetics (Greek: αισθητική; English: Aesthetic) is a sub-discipline of philosophy founded by the German philosopher Alexander Gottlieb Baumgarten in 1750. It was initially defined as the science of sensory knowledge (Ästhetik). The Greek root 'aesthesis' means sensory perception, and its study covers aesthetic activities, philosophy of art, and the world of imagery. Baumgarten's concept of 'sensory science' emphasizes that sensory cognition grasps the completeness of relationships between things in a quasi-rational way. Meanwhile, the French scholar Charles Batteaux in 1746 first proposed a system of 'fine arts' covering poetry, painting, and other forms. Hegel limited aesthetics to the philosophy of fine art, while Kant established the independent status of aesthetic judgment in the Critique of Judgment.
Area refers to the size of the space that an object's surface or a closed shape occupies on a two-dimensional plane, used to measure how much a 2D region is covered.
Area is how much space a shape takes up, while perimeter is how long the edges of the shape are. One is for measuring the size of the surface, the other is for the length of the edges, and their units are different too.
The area under the curve, the area under the curve, the area under the curve, usually refers to the area of the region enclosed by the curve and the axes. This area can be calculated using definite integrals. The exact method depends on the equation of the curve and the limits of integration.
An acute triangle is a triangle where all three interior angles are less than 90 degrees. It's one type of triangle based on angles, the other two being right triangles and obtuse triangles.
Adjacent angles in a quadrilateral are the two angles that share a side. The feature of adjacent angles is that their sum equals 180 degrees. For any quadrilateral, whether it's a rectangle, square, or parallelogram, the sum of adjacent angles is always 180 degrees.
Astronomy mainly studies celestial bodies in outer space, the structure and development of the universe, including the positions, structures, properties, and movement patterns of these bodies.
(1) Problems involving finding speed and distance during movement, (2) Problems about finding the tangent of a curve, (3) Problems about finding length, area, volume, and center of mass, (4) Problems about finding maximum and minimum values (quadratic functions, a type of calculus).
