1. | 1. Use the winder to make the knots scratch the thin plastic plate <br> | ||
2. | 2. Wind the thread until the red section crosses the thin plastic plate <br> | ||
3. | 3. Move the winder forward to add "knot-scratches" <br> | ||
4. | 4. Move the winder forward to subtract "knot-scratches" <br> | ||
5. | 5. Enter your calculation <br> | ||
5. Wind back to the red mark and count the "scratches"- they represent the result of your calculation!<br> | |||
