Hi Darryl, the 5 are: strictly less than (<), strictly greater than (>), less than or equal to (<=) greater than or equal to (>=) and different to (≠). Hope that helps!

The 5 that we use most are

1) Greater than

2) Less that

3) Equal to

4) Greater than or equal to

5) less than or equal to

There is also an identity (like an equals but with three lines instead of two). This is usually used in algebra - you can find this on a higher paper.

We can express inequalities as symbols or number lines or even be asked to solve an inequality.

Greater Than (>): This inequality symbol (>), read as "greater than," denotes that the value on the left is larger than the value on the right.

Example:

5

>

3

5>3

Less Than (<): The symbol (<), read as "less than," indicates that the value on the left is smaller than the value on the right.

Example:

2

<

7

2<7

Greater Than or Equal To (

≥): This symbol (

≥), read as "greater than or equal to," signifies that the value on the left is either greater than or equal to the value on the right.

Example:

4

4

4≥4

Less Than or Equal To (

≤): The symbol (

≤), read as "less than or equal to," means that the value on the left is either less than or equal to the value on the right.

Example:

6

6

6≤6

Not Equal To (

=): The symbol (

=), read as "not equal to," indicates that the values on both sides are not the same.

Example:

3

8

3

=8

Fortunately there is only one equality, which means there are plenty of inequalities! So,

A scalene triangle, its the left out triangle where none of the sides are equal!

But technically the definitions of inequality are not equal to, greater than, less than, greater than or equal and less than or equal.

The last two might be equal, but cannot be assumed.
