Checking Your Work

Double-Check for Success

After solving a problem, always check your work. Plug your answer back into the equation or review your steps to make sure you didn't miss anything. This helps catch small mistakes and builds your confidence.

  • Compare your answer to the question.
  • Make sure your units and labels are correct.

Examples

  • Plug your solution for \( x \) back into the original equation to see if it works.

  • Add up all angles in a triangle; they should total 180 degrees.
