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 '<' represent in an inequality?

Back

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

Front

What does the symbol '>' represent in an inequality?

Back

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

Front

What does the symbol '≤' represent in an inequality?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 10 means x is less than or equal to 10.

Front

What does the symbol '≥' represent in an inequality?

Back

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

Front

How do you express 'at most' in an inequality?

Back

'At most' is expressed using the symbol '≤'. For example, 'at most 100' is written as x ≤ 100.

Front

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

Back

'At least' is expressed using the symbol '≥'. For example, 'at least 50' is written as x ≥ 50.

Front

Write an inequality for: 'The temperature is less than 30 degrees.'

Back

t < 30

Front

Write an inequality for: 'The score must be at least 75 to pass.'
