Slide Rule Calculator

A slide rule is a manual calculation tool that uses logarithmic scales to perform multiplication, division, and other functions. With a fixed scale and a sliding scale, you add or subtract logarithms to perform arithmetic operations.

Key Concepts:

• Multiplication: Align the “1” on the sliding scale with the first number on the fixed scale; the second number’s position on the sliding scale gives the product on the fixed scale.
• Division: Align the second number on the sliding scale with the first number on the fixed scale; then the “1” on the sliding scale points to the quotient on the fixed scale.
• The scales are logarithmic: the position for a number x is proportional to log₁₀(x).

This app simulates a simplified slide rule to help you visualize and perform multiplication and division by representing the scales graphically.
