List of Math Terms That Start With V With Definitions and Examples
In Mathematics, many important words start with the letter ‘V’. These are important to learn and add to your dictionary. It will not only make a better understanding of the subject, but you can differentiate with their meaning as used in the English language.
Let’s read the article till end to know more about some maths words that start with v which are widely used.
Maths Words that Start with Letter V
1. Variable: A variable is a mathematical alphabet or any symbol that is used to represent any quantity or value. It is widely used in coordinate geometry or anywhere the equations are used.
For example: 2x + 3y = 20; Here, x and y are variables.
2. Vector: Vector is a quantity that has both magnitude and direction. Displacement and Velocity are vector quantities. Any vector quantity is represented by adding a vector sign (→) over a variable.
3. Velocity: As we know, velocity is a vector quantity. It tells the speed of an object along with its direction. Velocity is equal to the displacement of an object with respect to the time taken to cover the distance.
4. Venn Diagram: It is the pictorial representation of mathematical or logical sets. They are generally made of circles and enclosed in a rectangle to represent a universal set.

5. Vertex: A vertex is a point where two lines or one line and a curve or two curves meet at a point. The plural of vertex is ‘vertices’. A triangle has three vertices, a rectangular figure and a square has four vertices, a pentagon has five vertices, and so on. If we make an angle, then there will be only one vertex that made where two rays met at each other.
6. Vertical Axis: The axis which is perpendicular to the horizontal plane or horizontal axis is called the vertical axis. In general, it is denoted as the Y-axis.
7. Vertical Angles: The angles formed by the two intersecting lines are called vertical angles. Vertical angles, a and b are shown in the below figure:

8. Volume: The space occupied or enclosed within a 3-dimensional object or solids is called volume. It is usually denoted by the English alphabet ‘V’. There are various methods and certain formulas to evaluate the volume of an object. Some of the formulas to evaluate the volume of fixed shape objects are following:
Volume of Cube = side x side x side
Volume of Cuboid = length x breadth x height
The volume of Sphere = V = $\frac{4}{3}$πr3, where r is the radius of the sphere.
9. Vigesimal: Vigesimal is the number system based on ‘20’.
10. Value: Value is any magnitude, quantity, or number that is used to denote any numerical amount by an algebraic term.
Do You Know?
A circle or sphere has no vertex.

FAQs on Math Words That Start With V Explained Clearly
1. What are some common math words that start with V?
Common math words that start with V include variable, value, vector, vertex, volume, vertical, variation, vinculum, Venn diagram, and velocity. These terms are used across algebra, geometry, trigonometry, and statistics. For example:
- Variable – a symbol representing an unknown number
- Volume – the space inside a 3D shape
- Vertex – a corner point of a shape
These vocabulary words are essential for understanding core mathematics concepts.
2. What is a variable in math?
A variable is a symbol, usually a letter, that represents an unknown or changeable number. In algebraic expressions and equations, variables allow us to generalize patterns and solve problems. For example:
- In 2x + 5 = 11, the variable is x.
- Solving gives x = 3.
Variables are fundamental in algebra, equations, formulas, and functions.
3. What does value mean in mathematics?
In mathematics, value refers to the numerical worth of a number, expression, or variable. It can represent:
- The result of a calculation (e.g., the value of 3 + 4 = 7)
- The solution to a variable (e.g., if x = 5, then the value of x is 5)
- Place value in numbers (e.g., in 345, the 4 has a value of 40)
Understanding value is key in arithmetic, algebra, and number systems.
4. What is a vector in math?
A vector is a quantity that has both magnitude and direction. Vectors are commonly used in geometry, physics, and linear algebra. They are often written as:
- v = (x, y) in 2D space
- v = (x, y, z) in 3D space
For example, the vector (3, 4) has magnitude √(3² + 4²) = 5. Vectors are important in coordinate geometry and transformations.
5. What is a vertex in geometry?
A vertex is a point where two or more line segments, edges, or rays meet. In geometry:
- A triangle has 3 vertices.
- A square has 4 vertices.
- A parabola has one vertex, which is its turning point.
In coordinate geometry, the vertex of a parabola in the form y = a(x − h)² + k is (h, k).
6. What is the formula for volume?
The volume of a 3D shape measures the amount of space it occupies, and the formula depends on the shape. Common volume formulas include:
- Cube: V = s³
- Rectangular prism: V = l × w × h
- Cylinder: V = πr²h
- Sphere: V = (4/3)πr³
Volume is measured in cubic units such as cm³ or m³.
7. What does vertical mean in math?
In mathematics, vertical describes a line that goes straight up and down and has an undefined slope. In coordinate geometry:
- A vertical line has the form x = a, where a is a constant.
- Its slope is undefined because division by zero is not possible.
Vertical lines are perpendicular to horizontal lines.
8. What is direct variation in math?
A direct variation describes a relationship where one variable changes proportionally with another. It is written as:
- y = kx, where k is the constant of variation.
For example, if k = 3, then y = 3x. If x = 2, then y = 6. Direct variation graphs as a straight line passing through the origin.
9. What is a Venn diagram in mathematics?
A Venn diagram is a visual representation of sets using overlapping circles to show relationships between groups. It helps illustrate:
- Union (A ∪ B)
- Intersection (A ∩ B)
- Complement of a set
Venn diagrams are commonly used in probability, logic, and set theory to compare data.
10. What is velocity in mathematics?
In mathematics and applied math, velocity is the rate of change of position with respect to time and includes direction. It is calculated as:
- Velocity = displacement ÷ time
For example, if an object moves 100 meters north in 20 seconds, its velocity is 5 m/s north. Velocity differs from speed because it includes direction.
