Calculators: From Basic Arithmetic to Advanced Computing
A calculator is a device or tool used to perform mathematical calculations quickly and accurately. From simple addition to complex scientific computations, calculators have become essential in education, engineering, business, and everyday problem-solving.
Early civilizations used abacuses (dating back to 2400 BCE) for counting and arithmetic. Mechanical calculators appeared in the 17th century, but the first electronic calculator was developed in the 1960s. Today, calculators exist in physical, software, and online forms, making math more accessible than ever.
