List of Maths Glossary Words Starting With E with Definitions and Examples

Maths is one of the unique languages of science that deals with numbers and builds logical thinking and analytical reasoning skills. So, Maths vocabulary plays a very crucial role in understanding the Maths concepts better and developing Maths skills. Many times, we see that students are unable to process or make sense of what they are doing. If a student is unable to develop a Maths concept fully, then it will lead to a misconception and lack of understanding of the next skills because this is a building-block process. Therefore, students should have these foundational building blocks to advance to higher levels.


So, in this article, we will introduce you to the list of Mathematical words or terms that start with the letter ‘e’ which will help you to boost your Mathematical vocabulary skills.


List of Mathematical Words Starting with the Letter ‘E’

In this section, we have explained some of the Mathematical terms that start with ‘e’ in detail with examples. So, try to explore all the words and save as much as possible in your vocabulary bank.


Edge

In Geometry, an edge is a line segment that joins one vertex to another.


Example: A cube has 12 edges.


In Geometry, an edge is a line segment that joins one vertex to another.

Endpoints

In Geometry, the points on either end of a line segment or one end of a ray are called endpoints.


Example:


In Geometry, the points on either end of a line segment or one end of a ray are called endpoints.

Even Numbers

An even number is a number that can be divisible by 2 and after dividing even numbers by 2, we get 0 as a remainder. So, we can say that the numbers ending with 0, 2, 4, 6, and 8 are even numbers.

Equilateral Triangle

In Geometry, an equilateral triangle is a triangle that is composed of three sides equal in length and all the angles are equal in measure in an equilateral triangle.


Example:


In Geometry, an equilateral triangle is a triangle that is composed of three sides equal in length and all the angles are equal in measure in an equilateral triangle.

Equivalent Fractions

In Mathematics, equivalent fractions can be defined as the fractions that might have different denominators and numerators but are equal to the same value. All equivalent fractions result in the same fraction in their simplest form.


Example: 1/4, 2/8, 4/16, 8/32 — all the fractions represent the same value that is 1/4. So, all these are equivalent fractions.


Equation

In Maths, an equation is defined as a Mathematical statement that is composed of two algebraic expressions with the same value connected by an equal sign.


The algebraic expressions in Maths can have one or more than one variable.


Example: 5x + 10y = 20 is an equation where 5x + 10y and 20 are two expressions, connecting by an equal sign.

Element of a Set

All the objects or items present in a set are called elements. All the elements in a set are separated by commas and enclosed by curly brackets.


Example: A={2, 4, 6, 8, 10} is a set where 2, 4, 6, 8, 10 are the elements of the set A.


Empty Set

An empty set can be defined as a set that has no elements. It is also called a null set and is represented as {} or it can also be represented by using the symbol '∅'.


Exponent

An exponent can be defined as a number that tells you how many times a number is multiplied by itself. Exponent is also represented as the power of a number.


Example: 4×4×4 is the expanded form of 43 where 4 is multiplied by itself three times. Here, ‘3’ is called the exponent or power and ‘4’ is called the base.


Expanded Form

Expanded form is a way of showing up a number as a sum of each digit multiplied by its place value.


Example: 7892 can be expanded as 7000+800+90+2.


Conclusion

In this article, we have covered the most important Mathematical terms with examples which start with the letter ‘e’. Students need to practise and learn these concepts so that they don’t face any difficulties while solving problems at higher levels.

FAQs on Maths Terms That Start With the Letter E

1. What are common Maths glossary words that start with the letter E?

Common Maths glossary words starting with E include Equation, Expression, Exponent, Even number, Edge, Estimate, Evaluate, Expansion, Elimination method, and Experimental probability.

  • Equation: A mathematical statement showing two expressions are equal.
  • Expression: A combination of numbers, variables, and operations without an equals sign.
  • Exponent: Indicates repeated multiplication.
  • Even number: An integer divisible by 2.
  • Edge: A line segment where two faces meet in a 3D shape.
These terms are frequently searched in Maths glossary and vocabulary lists.

2. What is an equation in Maths?

An equation is a mathematical statement that shows two expressions are equal using an equals sign (=).

  • Example: 2x + 3 = 11
  • To solve: Subtract 3 from both sides → 2x = 8
  • Divide by 2 → x = 4
Equations are used in algebra to find unknown values and solve real-life problems.

3. What is the difference between an expression and an equation?

The main difference is that an expression has no equals sign, while an equation contains an equals sign.

  • Expression example: 3x + 5
  • Equation example: 3x + 5 = 20
An expression can be simplified, while an equation can be solved to find the value of a variable.

4. What is an exponent in Maths?

An exponent shows how many times a number is multiplied by itself.

  • Example: 2³ = 2 × 2 × 2 = 8
  • In aⁿ, “a” is the base and “n” is the exponent.
Exponents are also called powers or indices and are important in algebra and scientific notation.

5. What is an even number?

An even number is any integer that is divisible by 2 without a remainder.

  • Examples: 2, 4, 6, 8, 10
  • General form: 2n, where n is an integer
If a number ends in 0, 2, 4, 6, or 8, it is an even number.

6. What does evaluate mean in Maths?

To evaluate in Maths means to calculate the value of an expression by substituting numbers and performing operations.

  • Example: Evaluate 3x + 2 when x = 4
  • Substitute: 3(4) + 2
  • Result: 14
Evaluating expressions is a key algebra skill.

7. What is estimation in Maths?

An estimate is a value that is close to the exact answer, found by rounding or approximating.

  • Example: 49 + 32 ≈ 50 + 30 = 80
Estimation helps check if answers are reasonable and is commonly used in mental maths and real-life calculations.

8. What is expansion in algebra?

In algebra, expansion means removing brackets by multiplying terms inside them.

  • Example: 3(x + 4)
  • Multiply: 3·x + 3·4
  • Result: 3x + 12
Expansion uses the distributive property and is essential in simplifying algebraic expressions.

9. What is the elimination method in linear equations?

The elimination method is a technique used to solve simultaneous equations by eliminating one variable.

  • Example: x + y = 10 and x − y = 2
  • Add equations → 2x = 12
  • Solve → x = 6
  • Substitute back → y = 4
This method is widely used in solving systems of linear equations.

10. What is experimental probability?

Experimental probability is the probability of an event based on actual experiments or observed data.

  • Formula: Experimental Probability = (Number of times event occurs) / (Total number of trials)
  • Example: If a coin lands heads 6 times out of 10, probability = 6/10 = 0.6
It differs from theoretical probability, which is based on expected outcomes.
