Although there is delicious food, I don't know how delicious it is if I don't eat it. Although you have good knowledge, if you don't study them, you don't know what is good about it. Because of the above reasons, learners can understand their own shortcomings only after studying. In the process of teaching others to solve problems, teachers will also encounter places they don't understand. Students can reflect on themselves when they know their own shortcomings; Teachers who understand their own confusion will definitely strive for self-improvement. The above is the reason why education and learning promote each other and complement each other.
As the saying goes,' Mathematics complements each other', which means that the above is the truth that education and learning promote each other and complement each other.
