What does 'inequality' mean in mathematics?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

What is a variable in algebra?

Back

A variable is a symbol used to represent an unknown value in mathematical expressions and equations.

What is the purpose of solving equations?

Back

The purpose of solving equations is to find the value of the variable that makes the equation true.

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate an equation so that the variable is on one side and all other terms are on the opposite side.

Front

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.
