Can you remember any Maths term which starts with the letter ‘L’? There are several such terms in Mathematics; for example, line, length, least common factor, and many more. These terms are important and one must know about the meanings of these terms. Therefore, in this article, we have provided you with a list of words starting with the letter ‘L’ along with their Mathematical meaning.


List of Maths Terms Starting with ‘L’

Given below are some of the important Mathematical terms starting with the letter L. Knowing these terms will help you to understand the concepts of Mathematics easily.

  1. Least Common Denominator: The least common denominator (LCD) can be defined as the smallest number which is also a common denominator for a given set of fractions. It is also known as the lowest common denominator.

  2. Least Common Multiple (LCM): The least common multiple of a set of integers is the smallest integer that is an exact multiple of every number in the set.

  3. Least Upper Bound: The least upper bound of a set of numbers is the smallest number that is larger than every member of the set.

  4. Legs of a Right triangle: The two sides that are not the hypotenuse. The legs are the two sides that are on either side of the right (90 degrees) angle.

  5. Length: The straight line distance between any two points.

  6. Less Than: Having a smaller value than the given.

  7. Line: Line can be defined as the distance between two points and is represented by joining the two points.

  8. Line Graph: It is a diagram showing a system of connections or interrelations between two or more things by using lines.

  9. Line Segment: It is a piece of a line with endpoints at both ends.

  10. Line Symmetry: If a figure is divided by a line and both divisions are mirrors of each other, the figure has line symmetry. The line that divides the figure is the line of symmetry.

  11. Linear: An equation or graph is linear if the graph of an equation is a straight line.

  12. Linear Function: A function of the form f(x) = mx + b where m and b are some fixed numbers. The names “m” and “b” are traditional. Functions of this kind are called “linear” because their graphs are straight lines.

  13. Linear Regression: An attempt to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered as the independent variable, and the other is considered as the dependent variable.

  14. Locus: The set of all points meeting some specified condition.

  15. Logarithm: The exponent of the power to which a base number must be raised to equal a given number.

  16. Long Division: In Maths, long division is a method used for dividing large numbers into groups or parts. The long division helps in breaking the division problem into a sequence of easier steps. Just like all division problems, a large number, which is the dividend, is divided by another smaller number, which is called the divisor, to obtain a result called the quotient and sometimes a remainder.


We hope this list has helped you learn about some important Mathematical terms and their meaning. There are a lot more terms that start with the letter L. We advise you to go through these terms regularly to be familiar with their definitions and meanings.

FAQs on Maths Terms Starting with Letter ‘L’

1. What does the L stand for in Mathematics?

In Mathematics, the letter L is used as a symbol to represent different things based on the situation. For example, the small “l”  is used as a symbol for length, similarly, it is also used as a symbol for litres. 

2. What is a Line of Symmetry?

We often find symmetry in things around us. We say there is symmetry when the exact reflection or mirror image of a line, shape or object gets created. The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.
