Slide Rule Simulator

Slide Position: 0
Cursor Position: 50%

How to Use

This is a basic simulation of a slide rule with logarithmic scales:

  • Drag the middle section to slide the D scale left and right
  • Drag the red cursor to position it over numbers for calculations
  • The scales represent logarithmic values from 1 to 10
  • Use the reset buttons to return to starting positions

Basic Multiplication Example: To multiply 2 × 3, align the "1" on the D scale (middle) with "2" on the C scale (top), then find "3" on the D scale and read the answer on the C scale above it.
