# Math Expressions

> Enter a mathematical response and check its structure

Math-expression questions give you one math field for your response. Enter the expression or equation requested in the prompt, using the same variable names.

## Enter Your Answer

<Steps>
  <Step title="Check the Requested Form">
    Read whether the question asks for an expression, an equation, or an inequality. Include an equals sign only when your answer should be an equation.
  </Step>

  <Step title="Build Your Response">
    Click the math field and enter your answer. Use the [math editor guide](/general/tools/math-editor) for fractions, powers, roots, and the on-screen keyboard.

  </Step>

  <Step title="Check the Formatted Expression">
    Make sure each fraction bar, root, and exponent covers the terms you intended. Fill any empty boxes, then continue to the next question.

## How Answers Are Compared

For questions with a correct answer, Uflo compares your math with the expected answer. It can recognize equivalent expressions, such as `x + x` and `2x`, even when they look different. A matching response earns the question's full points; an unmatched response earns no points.

<Tip>
  Keep your final response focused on the requested answer. If the question asks for an expression such as `2x`, adding `y =` changes it into an equation.
