Calculators

Calculators are electronic or mechanical devices that perform mathematical calculations. They range from simple arithmetic tools to sophisticated scientific and financial instruments. Modern calculators typically feature a display screen, a keyboard with numeric and operational keys, and internal processing capabilities. They can perform basic operations like addition, subtraction, multiplication, and division, as well as more complex functions such as trigonometric, logarithmic, and statistical calculations. The core function is to expedite computation and improve accuracy, reducing human error in numerical tasks. From students to engineers, various professionals use them. They are often battery or solar powered. Advanced ones can store formulas and perform symbolic manipulations.
