What type of calculators are prohibited during the knowledge test?

• A. Calculators incorporating permanent memory circuits, magnetic cards, or any device that stores pre-written programs
• B. Basic four-function calculators without memory
• C. No calculators allowed
• D. Solar-powered calculators

Answer: (A)

The main rule here is that the test allows only calculators that have no ability to store data or run pre-written programs. Calculators with permanent memory circuits, magnetic cards, or any device that stores pre-written programs are prohibited because they could retain or load content from outside sources, which would undermine the integrity of the test.

That’s why the best answer points to calculators that include memory or program storage as the restricted type. Basic four-function calculators without memory are allowed, so they are not the prohibited type. Saying no calculators are allowed would be too broad, since memoryless, simple calculators are permitted. Solar-powered calculators aren’t inherently prohibited, as long as they don’t have memory or pre-programmed content; the key issue is memory/storage, not the power source.
