Function of addition table

1, Basic Arithmetic Training: Addition table is the basic tool of addition operation. By studying and using the addition table, students can master the basic rules and calculation methods of addition and improve their arithmetic ability.

2. Convenient calculation: the addition table can help students to perform addition calculation quickly. When calculating the sum of two numbers, students can get the answer directly by looking up the addition table, which greatly improves the efficiency and accuracy of calculation.

3. Cultivate logical thinking: using the addition table to calculate requires students to have certain logical thinking and reasoning ability. Repeated use of the addition table can train students' logical thinking and reasoning ability and improve their mathematical literacy.

4. Auxiliary teaching: Addition table is an important auxiliary tool in mathematics teaching. Teachers can use addition tables in classroom teaching to help students understand and master the rules and methods of addition operation. At the same time, the addition table can also be used as self-study materials for students to help them consolidate their mathematics knowledge.
