When two numbers are not equal, an a0 is a sentence that uses the symbols > , < , ≥, ≤, or ≠ to show a relationship.

A math sentence using those symbols is called an inequality.

When two numbers are not equal, inequality ( ≠ ) symbol is use to show relationship.

Step-by-step explanation:

Greater than ( > ) {a > b} symbol is used to show a is greater than b.

Less than ( < ) {a < b} symbol is used to show a is less than b.

Greater than or equal to ( ≥ ) {a ≥ b} symbol is used to show a is larger than or equal to b.

Less than or equal to ( ≤ ) {a ≤ b} symbol is used to show a is smaller than or equal to b.

Not equal to ( ≠ ) {a ≠ b} symbol is used to show a is not equal to b.
