The term 'oval shape in math' can be summarized as an ELLIPSE, which is a 7-letter word. An ELLIPSE is a closed curve in a plane, which is formed by the intersection of a cone with a plane that cuts it. It is a type of conic section, and is the locus of all points in the plane whose distances to two fixed points add up to the same constant. Ellipses are used in many areas of mathematics, including geometry, astronomy, and engineering.
