Two axis span a plane containing a curve. Two points on the curve are labeled "P" and "Q", and a violet line passing through them intersects the curve in a third point. A violet vertical line passing through this third point intersects the curve at a fourth point, labeled "P + Q". — The geometric group law of an elliptic curve
