    • Options include:
      • Multiply (×) – multiply your chosen constant by a number.
      • Divide (÷) – divide a number by the constant.
      • Power (^) – raise the constant to an exponent.
      • Root (√) – find the nth root of the constant.
  3. Enter a Value
    • Depending on the operation, input the required value (e.g., a multiplier, divisor, exponent, or root degree).
  4. Click “Calculate”
    • The tool processes your input and displays the result with the exact formula used.
  5. View the Results
    • See your answer along with a tip about the selected constant for better understanding.

Practical Example

Let’s say you’re working on a geometry problem and need to multiply π (Pi) by 10.

  • Step 1: Choose π (Pi) from the dropdown.
  • Step 2: Select Multiply (×).
  • Step 3: Enter the value 10.
  • Step 4: Click Calculate.

The tool shows:

  • Result (10 × π): 31.4159265359
  • Formula: 10 × π = 31.4159265359
  • Tip: Pi (π) is the ratio of a circle’s circumference to its diameter.

This makes it extremely useful for quick geometry, trigonometry, or physics-related calculations.
