•  A calculator is a device or tool used for performing mathematical calculations. It allows users to perform basic arithmetic operations such as addition, subtraction, multiplication, and division, as well as more complex calculations involving functions, percentages, and exponentiation.
  • Modern calculators come in various forms, including physical handheld calculators, software calculators on computers and smartphones, and online calculators accessible through web browsers.
  • Here are some common features and functionalities found in calculators:

  • Basic Arithmetic Operations: Addition (+), Subtraction (-), Multiplication (*), and Division (/) are the fundamental arithmetic operations performed by calculators.

  • Memory Functions: Many calculators have memory storage features that allow you to store and recall numbers for later use.

  • Scientific Functions: Advanced calculators often include scientific functions such as square root, logarithms, trigonometric functions (sine, cosine, tangent), exponentiation, and more.

  • Percentage Calculations: Calculators can calculate percentages, including finding a percentage of a number, percentage increase or decrease, and percentage of a whole.

  • Parentheses and Order of Operations: Calculators follow the order of operations (PEMDAS/BODMAS) to evaluate complex mathematical expressions involving parentheses, exponents, multiplication, division, addition, and subtraction.

  • Decimal Precision and Rounding: Calculators allow you to choose the decimal precision and rounding options based on your desired level of accuracy.

  • Conversion Functions: Some calculators have built-in conversion functions for converting between units of measurement, such as length, weight, temperature, and more.

  • Financial Functions: Certain calculators offer specialized financial functions, such as calculating loan payments, interest rates, and mortgage calculations.

  • These are just some of the common features found in calculators. The functionalities and capabilities may vary depending on the type of calculator and its intended purpose.
