A permitted calculating device is a tool used during the mathematics section of a standardized college admissions assessment. Its purpose is to aid test-takers in performing complex calculations more efficiently and accurately than is possible with mental math or manual computation alone. Using one allows students to allocate their limited testing time strategically and focus on problem-solving rather than tedious arithmetic.
The allowance of such devices is a recognition that mathematical proficiency involves understanding concepts and applying them, not merely performing rote calculations. Their use allows the exam to assess a broader range of mathematical skills and knowledge. Initially, the use of such tools was limited; however, the policies have evolved to reflect changes in educational technology and the recognition of their value as a standard tool in mathematics coursework.
