The textbook on page 79 of the second volume of mathematics in grade two shows that bees travel in four directions. Among them, 365,438+00 bees fly north, 65,438+003 bees fly east, 286 bees fly south and 530 bees fly west, so 365,438+00 plus 65,438+003 plus 286 plus 530 equals 654,300.

This lesson focuses on addition and subtraction. This problem mainly uses the algorithm of addition. Addition is one of the four basic operations, which means that two or more numbers and quantities are calculated into one number and quantity.
