Mathematical problems of polygonal banana clock
38. In the first picture, a figure consists of a hexagon and a pentagon. A graph has 1 1 edges, so one edge is equal to 1.

Banana clock is easy to know that banana = 4, table = 3, a handful of bananas is four, table is three, so a banana = 1, two points =2.

For example:

The first formula: three (hexagon+pentagon+quadrilateral) =45.

Hexagon+Pentagon+quadrilateral = 15

Hexagon =6, Pentagon =5, quadrilateral =4.

The second formula: 4 bananas +4 bananas+15=23.

4 bananas =4

1 banana = 1

The third formula: 4 bananas +3 points +3 points = 10.

3 o'clock =3

1 point = 1

The fourth formula: 2 points +3 bananas +3 bananas × (hexagon+Pentagon)

2+3+3×(6+5)

=5+3× 1 1

=5+33

=38

Addition has several important properties. It is interchangeable, which means that the order is not important, it is interrelated, which means that when more than two numbers are added, the order in which the addition is performed is not important. Repeatedly adding 1 is the same as counting; Adding 0 will not change the result. Addition also follows related operations such as subtraction and multiplication.

Addition is one of the simplest digital tasks. The most basic addition: 1+ 1 five-month-old babies and even other animal species can be counted. In primary education, students are taught to calculate the superposition of decimal numbers, starting with one digit, and gradually solving the more difficult number calculation.
