What term describes a small electronic device used for mathematical calculations, typically with a keyboard and a visual display?

• A. Computer
• B. Calculator
• C. Laptop
• D. Smartphone

Answer: (B)

This question tests recognizing a device designed specifically for performing mathematical calculations. A calculator fits because it is a small electronic tool with a keypad and a display, built primarily for arithmetic and other math functions. Computers, laptops, and smartphones can do calculations, but they are general-purpose devices used for many tasks beyond basic math, whereas a calculator is defined by its focus on numeric calculations. So the term that best matches the description is calculator.
