Answer Checking and Error Prevention

Catch Mistakes Before They Cost You

Double-checking your answers can catch small errors that cost big points. Plug your answer back into the question, check units, and look for calculation slips.

  • Substitute your answer to verify.
  • Check if your answer makes sense in context.
  • Watch out for common traps, like sign errors or misreading the question.

Examples

  • After solving for \( x \), plug it back into the equation to verify.

  • If a length comes out negative, re-examine your work—distances can't be negative!
