Point addition on an elliptic curve is defined geometrically by drawing a line through two points A and B, finding its third intersection with the curve, and reflecting that intersection point across the x-axis to obtain the sum C.
Conditions: A and B are points on the elliptic curve.; The line through A and B intersects the curve at a third point.; The curve is symmetric about the x-axis.
