## Less Than Or Equal To

**Less than or equal to** relation is one of the inequalities used to represent the relation between two non-equal numbers or other mathematical expressions. We know that the ‘less than’ symbol is used to show that one quantity is lesser than the other quantity, and the ‘is equal to’ symbol is used to show that two quantities are equal. Similarly, there is a symbol of less than or equal to in math which is used to show that one quantity can be less than the other quantity or equal to the other quantity.

## Equal Sign With 3 Lines

The equal sign with two lines means something is equal to something. Example: a = 3, b = 9

The equal sign with three lines means that something is identical or similar to something but not necessarily equal. Thus, a triple equals sign means equivalent. The equivalent is not the same as equals. The double bar is more common and generally implies equality. In some contexts, the triple bar or equal sign with three lines means congruent or, more generally, an arbitrary equivalence relation.

## Using Equal To In An Equation

An equation is a statement of equality between two mathematical expressions that contains variables and constants. In every equation, the expression given on the left-hand side is equal to the expression given on the right-hand side .

For example: $5 + 3 = 8$

This means that the LHS is $5 + 3$ and it is equal to the RHS, which is 8.

If we have an equation $2x + 3 = 7$. It means that $2x + 3$, i.e., the expression given on LHS is equal to 8, i.e., the expression given on RHS.

Then we can deduce that $x=2$.

## Set Equality Based On First

In first-order logic with equality, the axiom of extensionality states that two sets which *contain* the same elements are the same set.

- Logic axiom:
*x*=*y**z*, - Logic axiom:
*x*=*y**z*, - Set theory axiom: )
*x*=*y*

Incorporating half of the work into the first-order logic may be regarded as a mere matter of convenience, as noted by Lévy.

- “The reason why we take up first-order predicate calculus
*with equality*is a matter of convenience by this we save the labor of defining equality and proving all its properties this burden is now assumed by the logic.”

## What Is The Difference Between Less Than And Less Than Or Equal To

The inequality ‘less than’ is represented by the symbol < whereas the inequality ‘less than or equal to’ is represented as . The inequality ‘less than’ means that some variable or number can have any value that is less than the given limit, not more than that or equal than that limit, but the inequality ‘less than or equal to’ states that the number or variable can be equal or less than the given limit. Here, the inclusion of the limit is the difference.

## Equal Groups As Repeated Addition

If we have multiple equal groups, then we can use repeated addition to find the total number of objects. Lets see how we can do that.

There are 4 groups, each having 6 stars. So, if we add the number 6 four times, we can find the total number of stars.

So, total number of stars $= 6 + 6 + 6 + 6 = 24$ stars.

## Less Than Or Equal To Examples

**Example 1: **A classroom can occupy 60 study tables at most. Express this statement using the less than or equal to symbol.

**Solution:**

Let’s represent the number of study tables by the variable x.

It is given that the classroom can occupy a maximum of 60 study tables.

So, this can be represented by a simple inequality.

x 60

Therefore, the condition is represented as x 60, where x is the number of tables.

**Example 2:** Charles had 18 chocolates which he was going to distribute to his friends on his birthday. Since the box was open, he lost some chocolates on the way. If x is the number of chocolates that Charles currently has, write an inequality using the ‘less than or equal to’ symbol that represents this situation.

**Solution:**

Number of chocolates Charles had initially = 18

Since he lost some chocolates, the number of chocolates with him currently is less than 18.

x < 18

We know that the number of chocolates should be a non-negative quantity. Hence,

x 0

This inequality can also be written as:

0 x

From the inequalities and , we get,0 x < 18

Therefore, the number of chocolates Charles has is represented as 0 x < 18.
