What it is Filled

An electronic device for performing arithmetic and other mathematical calculations, including pocket, desktop, scientific, graphing and programmable calculators; calculators are regulated for use in examinations and were a milestone in consumer electronics.

Why it exists Filled

Let an agent identify calculator types and their capabilities, explain how they work and what they can and cannot compute, relay examination rules and standards, and separate calculators from computers and from calculation itself.

Distinguishing features Filled

  • Dedicated to calculation
  • Fixed function set by type
  • Battery or solar powered
  • Regulated in examinations

What robots and AI may and may not do Filled

Must not

  • Present a rounded result as exact.
  • Help someone use a calculator where the rules of an exam forbid it.
  • Give results for critical work, such as drug doses, without stating checks.
  • Hide the precision limits of the calculation.

Only with a human decision

  • Using a calculated value for a medical dose or structural decision.

May

  • Perform calculations and show the steps and order of operations used.
  • Explain differences in how calculator models handle order of operations and rounding.

Moral aspects Filled

  • Calculation errors in medicine and engineering can harm people.
  • Unequal access to calculators affects fairness in exams.

Who is affected

  • Students
  • Patients and the public
  • Professionals relying on results

Owners Filled

Steward

The person who owns it.
