1, direct observation method: Some problems may be discovered by our direct observation. For example, if we see a question "10,20,30", then we can directly fill in 40 in the blank, because the next number in this regular series is obviously 50.
2. Logical reasoning: We can use logical reasoning to solve some problems that need us to fill in numbers. For example, if the question is "1, 2, 4", we can infer that the law of this series is that each number is twice the previous number, so the question mark should be 8.
3. Mathematical calculation method: Some questions may require us to do simple mathematical calculation to get the answer. For example, the question is "5, 1 1, 22". We can see that the law of this series is that each number is the previous number plus an increasing series, so the question mark should be 44.
The benefits of learning mathematics
1. Improve the ability of logical thinking and abstract thinking: Mathematics involves abstract concepts such as concepts, symbols, formulas and theorems. Learning mathematics needs the ability of logical thinking and abstract thinking, which helps to improve our logical thinking and abstract thinking ability.
2. Enhance the ability to solve problems: Mathematics involves the skills and methods of solving problems. Learning mathematics helps us to master the skills and methods of solving problems, thus improving our ability to solve problems. Mathematics involves skills such as calculation and data processing, and learning mathematics can improve our ability of calculation and data processing.
3. Cultivate creativity and innovative spirit: Mathematics is an important way to cultivate creativity and innovative spirit. By studying and applying mathematics, we can learn to discover, analyze and solve problems, and create new mathematical knowledge from them.
4. Provide more career opportunities: Mathematics is a subject widely used in various fields. Learning mathematics can give us more career opportunities in science, engineering, economy, finance and other fields.
5. Enhance self-confidence: Mathematics is a subject that needs to constantly challenge and surpass itself. By learning and mastering mathematics knowledge, we can enhance our self-confidence and improve our sense of self-worth.
