The Four Arithmetic Operations is an educational application developed for basic arithmetic skills: addition, subtraction, multiplication, and division.

With a massive database of tens of thousands of arithmetic operations, adding, subtracting, multiplying, and dividing questions, children are not afraid of any arithmetic problems.

Different difficulty levels of training modes provide the most suitable training for children.

Children need to quickly master the four basic operations of addition, subtraction, multiplication, and division during the transition from early childhood to early primary school

Four operations play a crucial role in learning mathematics. The age of 3-7 is an important period for laying a solid foundation in oral arithmetic, which will directly affect students future computing abilities. Due to their young age and immature psychological development, preschool children often make mistakes in calculation exercises. Scientific methods are used to improve their mental arithmetic skills. Therefore, this application covers addition and subtraction within 500, addition and subtraction within 500, and mixed addition and subtraction within 500.
