Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
May 2, 2024 · Algorithm: A procedure or set of steps used to solve a mathematical computation. Angle: Two rays sharing the same endpoint (called the angle vertex). Angle Bisector: The line dividing an angle into two equal angles. Area: The two-dimensional space taken up by an object or shape, given in square units.

A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. We indicate the position of a point by placing a dot with a pencil. This dot may have a diameter of, say, 0.2mm, but a point has no size. No matter how far you zoomed in, it would still have no width.
A unit for measuring angles, similar to degrees. 1 radian ≈ 57.3°. What makes radians special is this: An arc with an angle of 1 radian will have a radius (side length) that is the same as the arc length. A full circle has 2π radians, so 2π=360°. When using π, the term radians isn’t needed.

In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.
In math, a point is represented by a dot (.) and is used to tell exact location in space. It does not have any length, width, or height. In other words, it has no size. A point is usually named using uppercase letters. Let’s have a look at some points — A, B, C, and D.
The arithmetic mean is the sum of all of the data points divided by the number of data points. mean = sum of data # of data points. Here's the same formula written more formally: mean = ∑ x i n. Example. Find the mean of this data: 1 , 2 , 4 , 5. Start by adding the data: 1 + 2 + 4 + 5 = 12. There are 4 data points. mean = 12 4 = 3. The mean is 3 .
