Expression, Equation, or Inequality?

Front

What is an expression in mathematics?

Back

An expression is a combination of numbers, variables, and operators (such as +, -, *, /) that represents a value but does not include an equality or inequality sign.

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing an equals sign (=).

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other, using symbols like >, <, ≥, or ≤.

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

Back

The symbol '>' means 'greater than' and indicates that the value on the left side of the symbol is larger than the value on the right side.

Front

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

Back

The symbol '<' means 'less than' and indicates that the value on the left side of the symbol is smaller than the value on the right side.

Front

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

Back

The symbol '≥' means 'greater than or equal to' and indicates that the value on the left side is either greater than or equal to the value on the right side.

Front

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

Back

The symbol '≤' means 'less than or equal to' and indicates that the value on the left side is either less than or equal to the value on the right side.

Front

What is a linear equation?

Back

A linear equation is an equation of the first degree, meaning it involves only linear terms and can be written in the form ax + b = c, where a, b, and c are constants.

Front

How can you identify an inequality from an expression?

Back

An inequality can be identified by the presence of inequality symbols such as >, <, ≥, or ≤ in the expression.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows the relationship between two expressions that are not necessarily equal.
