Integer

1. Begin with two points, A and B, distance s apart.

2. Construct the line $$\overset{\longleftrightarrow}{A B}$$

3. Construct the circle $$\overset{\frown}{B A}$$. It intersects $$\overset{\longleftrightarrow}{A B}$$ at point C. The distance between A and C is 2s.

4. Each additional circle adds s to the distance. AD = 3s, AE = 4s, AF = 5s, etc.
