-A calculator is an electronic or mechanical device designed to perform mathematical operations automatically, ranging from basic arithmetic like addition, subtraction, multiplication, and division to more complex functions such as trigonometry, logarithms, and graphing.
- Modern electronic calculators, which became popular in the mid-1970s due to advancements in integrated circuits, are typically portable and use batteries or solar cells for power.
- They feature a keypad for input, a display (often LCD) for output, and a processor chip that executes calculations using built-in programs stored in permanent memory.
- While basic calculators handle simple operations, specialized types include scientific calculators for advanced math, graphing calculators for visualizing functions, and financial calculators for tasks like mortgage and investment calculations.

-A calculator is an electronic device or software application designed to perform mathematical computations with speed and accuracy. Ranging from basic handheld units that handle simple arithmetic—such as addition, subtraction, multiplication, and division—to complex scientific and graphing models capable of solving calculus problems and plotting data, these tools have become essential in education and professional fields. While originally mechanical, modern calculators are predominantly digital and are now ubiquitous, often integrated directly into smartphones and computers to assist with everything from daily budgeting to advanced engineering equations.
