Free online Scientific Calculator

This scientific calculator lets you perform both basic arithmetic and advanced mathematical operations. You can easily calculate sums, differences, products, and quotients, as well as work with trigonometric functions, logarithms, exponents, and constants like π and e. It also includes memory functions to store and recall your calculations for more efficient problem solving.

This calculator is a full-featured, scientific calculator offers both basic arithmetic and advanced functions—all wrapped in a modern, tactile design. Here’s a breakdown of what it does and how it works:

What It Does

  • Basic Arithmetic Operations:
    Users can perform addition, subtraction, multiplication, and division with a layout similar to classic handheld calculators. The numeric buttons and basic operators are arranged in an intuitive grid.
  • Scientific Functions:
    In addition to basic math, the calculator supports functions such as sine, cosine, tangent, natural logarithm (ln), common logarithm (log), and even the constant π. When you click one of these function buttons, it automatically appends an opening parenthesis so you can easily input the argument.
  • Memory Operations:
    Four memory functions are available:
    • MC (Memory Clear): Clears the stored memory value.
    • MR (Memory Recall): Retrieves the stored value.
    • M+ (Memory Add): Adds the current display value to the memory.
    • M- (Memory Subtract): Subtracts the current display value from the memory.
  • Additional Functions:
    Alongside standard operations, there are extra utility buttons:
    • Backspace (←): Removes the last character from the current input.
    • Toggle Sign (±): Switches the sign of the number.
    • Decimal Point (.) and Percentage (%): For floating-point and percentage calculations.
    • Square Root (√), Square (x²), and Reciprocal (1/x): For additional mathematical operations.
    • Factorial (x!): Replacing the redundant CE button, this new button calculates the factorial of a non-negative integer.

This design ensures that whether you’re doing everyday arithmetic or more complex scientific calculations, the tool remains user-friendly and efficient. Enjoy exploring both the simplicity of basic operations and the power of scientific functions in one sleek package!
