What is an inequality?

Back

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

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

Back

The symbol '>' means 'greater than'. For example, x > 2 means x is greater than 2.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. For example, x < 2 means x is less than 2.

Front

What does the symbol '≥' mean 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

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

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 2 means x is less than or equal to 2.

How do you represent an inequality on a number line?

Back

An inequality is represented on a number line by shading the region that satisfies the inequality and using an open dot for < or > and a closed dot for ≤ or ≥.

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in 5x, 5 is the coefficient of x.

Front

What is a variable in mathematics?

Back

A variable is a letter or symbol that represents an unknown number or value, such as x or y.

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 8 + 5x, 8 is a constant.

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than or less than another.
