The first-year oral math problems can cover addition and subtraction, and gradually introduce comprehensive calculation. Through these topics, students can consolidate the foundation of addition and subtraction operations and cultivate mathematical thinking and calculation ability. Oral calculation questions should be easy to understand, pay attention to students' basic calculation skills, gradually increase the difficulty and help students improve their problem-solving ability. These topics can stimulate students' interest in mathematics and let them study mathematics in a pleasant atmosphere.

Oral arithmetic is an important part of first-year students' learning mathematics foundation. Through these simple and interesting questions, they can cultivate their basic computing ability in a relaxed atmosphere and lay a solid foundation for further mathematics study in the future.
