For children's learning, math fundamentals are a crucial part. Arithmetic skills are the cornerstone of math learning. As an auxiliary learning tool, the multi-function arithmetic machine can help children improve their arithmetic skills and enhance their interest in math learning. This article will provide a detailed introduction to the usage of the multi-function arithmetic machine to help parents and children better utilize this tool. II. Guide to Using Multi-Function Arithmetic Machines 1. Startup and Interface Understanding First, open the multi-function arithmetic machine, and the main interface will be displayed on the screen. The main interface usually includes a number input area, an operation symbol selection area, and a result display area. Parents should first familiarize children with the basic composition of these interfaces. 2. Basic Arithmetic Practice The multi-function arithmetic machine usually has basic arithmetic functions such as addition, subtraction, multiplication, and division. Parents can choose appropriate operations based on the age and learning ability of the child for practice. For example, starting with simple addition and gradually increasing the difficulty. 3. Custom Questions and Modes In addition to basic arithmetic practice, the multi-function arithmetic machine also supports custom questions and modes. Parents can set parameters such as question range and difficulty according to the child's needs, allowing the child to practice in a targeted manner.

4. Timed and Challenge Modes Some multi-function arithmetic machines also have timed and challenge modes. The timed mode can help improve the child's calculation speed, while the challenge mode can increase the fun of learning and stimulate the child's interest in learning. 5. Error Collection and Learning Reports The multi-function arithmetic machine automatically records wrong questions for easy review by the child. Additionally, some arithmetic machines can generate learning reports to help parents understand the child's learning progress and weaknesses, so they can adjust the learning plan accordingly.
