Permitted calculating devices for the standardized college admission test encompass a range of models, primarily those with basic arithmetic, square root, and trigonometric functions. An example would be a standard scientific calculator; however, devices with computer algebra systems (CAS) are typically disallowed.
The allowance of these tools aims to provide test-takers with computational assistance, facilitating quicker solutions to math problems. Historically, permitting calculator use has been intended to level the playing field, reducing reliance on advanced mental math skills and focusing assessment on problem-solving abilities and mathematical reasoning.
