Front

Define an inequality.

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or equal to the other.

Front

What is the solution to the equation 55 + x = 145?

Back

To find x, subtract 55 from both sides: x = 145 - 55, so x = 90.

Front

What is the meaning of the term 'variable' in mathematics?

Back

A variable is a symbol, often represented by a letter, that stands for an unknown value.

Front

What is the difference between x > 1 and x ≥ 1?

Back

x > 1 means x is greater than 1 (not including 1), while x ≥ 1 means x is greater than or equal to 1 (including 1).
