The two programs, Onion Math and Euler Math, each have their own characteristics and are suitable for students with different needs. Let's go through the differences next.

Onion Math is an Internet-based math education platform that helps students easily master math knowledge through vivid video lessons and interactive learning methods. The platform covers multiple stages of elementary school math, middle school math and high school math, and provides a large number of practice questions and quizzes to help students consolidate what they have learned.

Oracle Math is a learning software that focuses on the development of mathematical thinking and guides students to discover mathematical laws and principles through a series of mathematical games, challenges, and investigative activities. The software not only covers elementary, middle and high school math, but also includes some introductory knowledge of college math for students who have a strong interest in math.

In terms of teaching methods, Onion Math pays more attention to visualization and contextualization, transforming abstract mathematical concepts and formulas into easy-to-understand forms, which is suitable for students with a weaker foundation. On the other hand, Euler's Math pays more attention to cultivating students' mathematical thinking and problem-solving ability, which can better expand their mathematical vision and improve their mathematical literacy for students who already have a certain mathematical foundation.

In summary, the choice depends on the student's personal needs and learning style. If you need to learn math comprehensively and focus on mastering the basics, you can choose Onion Math; if you have a strong interest in math and want to expand your math thinking and horizons, you can choose Euler Math.
