In this kind of topic, we need to observe the relationship between figures or numbers, find out the rules, and complete the subsequent drawing tasks according to the rules.
1. Look carefully: You need to look carefully at the figures or numbers given in the title to find out the relationship between them. This may include the relationship between shape, size, color and position.
2. Analysis of laws: After finding the relationships between figures or numbers, we need to analyze these relationships and find out the laws. For example, if the topic requires you to draw a series of increasing numbers, then you need to find out the increasing law between these numbers (for example, each increase 1).
3. Apply the rule: According to the found rule, you can start to draw the next figure or number. Make sure your painting meets the requirements of the topic, such as keeping the same proportion, direction, etc.
4. Check the answer: After drawing, you need to check whether your answer meets the requirements and laws of the topic. If necessary, you can modify your drawing to better meet the requirements of the theme.
5. Practice and summary: Through constant practice and summary, you can improve your ability to discover laws and draw. At the same time, you can also try to find different solutions to the problem, so that when you encounter similar problems, you can find a solution faster.
Mathematical laws:
1, additive commutative law: When two numbers are added, the order is irrelevant, for example, a+b = b+a.
2. Law of addition and association: When multiple numbers are added, the grouping method does not affect the result, such as (a+b)+c=a+(b+c).
3. Multiplication and exchange law: When two numbers are multiplied, the order of factors can be reversed, such as ab=ba.
4. Multiplication and association law: multiple numbers are multiplied, and the grouping method does not affect the result, such as abc=a(bc).
5. Multiplication and distribution law: When one number is multiplied by the sum of the other two numbers, it means that this number is multiplied by these two numbers and then added, that is, a(b+c)=ab+ac.
6. Power: a number multiplied by its own power is equal to the square of the power of this number, that is, (AB) n = a n * b n
7. same base powers division: the power division of two numbers with the same base is equal to the constant base and exponential subtraction, that is, a m/a n = a (m-n).
8. same base powers multiplication: two powers with the same base are multiplied, which is equal to the same base, and the exponents are added, that is, a m * a n = a (m+n).
9. Exponential power of zero: the power of zero of any non-zero number is equal to 1, that is, a 0 = 1 (when a≠0).
10, negative integer exponential power: the power of any non-zero number-1 is equal to its reciprocal, that is, a (- 1) = 1/a (when a≠0).
