The specific problem solving process is as follows:
1. If the turtles are arranged in a row (the first one is not next to the last one), the number of rabbits is 18, as shown in the figure (1 rabbit equals 2 rabbits):
2. If the turtles are arranged in a circle (the first one is not next to the last one), the number of rabbits is 20, as shown in the figure (1 rabbit equals 2 rabbits):
Extended data:
Circle: On the plane, a closed curve formed by a moving point rotating around a certain point with a certain length is called a circle. A circle has countless points.
Mathematics (Mathematics or maths, from the Greek word "Má thē ma"; Often abbreviated as "mathematics"), it is a discipline that studies concepts such as quantity, structure, change, space and information, and belongs to a formal science from a certain point of view. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for studying and studying modern science and technology.
