What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. For example, x > 3 means x is greater than 3.

Front

What does the symbol '<' mean?

Back

The symbol '<' means 'less than'. For example, y < 5 means y is less than 5.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'. For example, z ≥ 2 means z is greater than or equal to 2.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. For example, a ≤ 7 means a is less than or equal to 7.

Front

How do you represent 'at least' in an inequality?

Back

'At least' is represented by the symbol '≥'. For example, 'at least 80' is written as x ≥ 80.

Front

How do you represent 'more than' in an inequality?

Back

'More than' is represented by the symbol '>'. For example, 'more than 4' is written as x > 4.

Front

How do you solve the inequality x - 3 ≤ 4?

Back

Add 3 to both sides: x ≤ 7.

Front

What is the solution to the inequality 2 + x < 1?

Back

Subtract 2 from both sides: x < -1.

Front

What is the solution to the inequality q - 8 ≤ -9?

Back

Add 8 to both sides: q ≤ -1.
