Whether for elementary school students or adults, mastering the skills of mental calculation is the key to improving mathematical ability. This article will guide readers from the basic to advanced stages, gradually mastering the mysteries of the mental calculation machine. Stage One: Master Basic Operations In the basic stage of mental calculation, we need to master the basic arithmetic operations of addition, subtraction, multiplication, and division. Through repeated practice, we can familiarize ourselves with the laws and techniques of these basic operations, forming the ability to quickly perform calculations in our minds. Stage Two: Master Operation Laws

After mastering basic operations, we can enter the advanced stage and begin to learn more complex operation laws. For example, we need to learn how to use basic mathematical principles such as the multiplication distribution law, association law, and commutative law to simplify complex calculation processes. In addition, we also need to master some quick arithmetic techniques, such as rounding methods and difference-quotient methods, to improve calculation speed and accuracy.
