A compact, typically numeric keypad arrangement consisting of ten digits (0-9), along with basic mathematical operation keys (+, -, *, /) and often including decimal point, clear, and enter keys. This configuration facilitates rapid and accurate numerical data entry, commonly used for accounting, bookkeeping, and financial tasks.

This input device streamlines tasks involving large volumes of numerical data, enhancing efficiency and minimizing errors compared to standard keyboard input. Its design, rooted in mechanical adding machines, prioritizes speed and accuracy, making it an indispensable tool in professions requiring significant numerical processing. It also allows for data to be input without the use of a mouse or trackpad.

Permitted calculating devices for the ACT are specific models allowed for use during the mathematics section of the standardized test. These devices are designed to aid in computation and problem-solving, but they must adhere to strict guidelines to ensure fairness and prevent any advantage over other test-takers. A scientific calculator, for example, is typically acceptable, while calculators with computer algebra system (CAS) functionality are generally prohibited.

Utilizing an approved calculator can significantly improve speed and accuracy during the ACT mathematics section. It allows test-takers to focus on understanding the problem and applying the correct mathematical principles, rather than spending excessive time on tedious calculations. Historically, the allowance of calculators has evolved to balance assisting students with complex computations and preventing the use of devices that offer unfair advantages, maintaining the integrity of the exam.
