Calculation rules of fractional multiplication
1. Fraction and integer multiplication: the product of numerator and integer multiplication is numerator, and the denominator remains unchanged.
2. Fractional multiplication: the product of numerator multiplication is the numerator and the product of denominator multiplication is the denominator. 3. In order to simplify the calculation, what can be reduced should be reduced first and then calculated. Note: When multiplying with a fraction, the fraction should be converted into a false fraction before calculation.
Significance of fractional division
The number A divided by the number B (except 0) is equal to the reciprocal of the number A multiplied by the number B. Elementary arithmetic is of the same order as integer elementary arithmetic, and it is easy to calculate by using the algorithm.
How to learn primary school mathematics well
First, lay a solid foundation in mathematics.
First of all, we should lay a good foundation in mathematics and master the basic operations of addition, subtraction, multiplication and division. These basic skills are the basis of learning other mathematical knowledge, so you should master them skillfully. You can consolidate your foundation through a lot of practice, and you can choose a problem set that is consistent with your own level to practice. At the same time, we should also understand the ideas and methods of solving each problem, and not just calculate it mechanically.
Second, cultivate mathematical thinking.
It is very important to cultivate good mathematical thinking in the process of learning primary school mathematics. We should pay attention to cultivating the ability to analyze and solve problems and be good at using logical reasoning and mathematical thinking. You can improve your math thinking ability by taking part in math competitions and solving some interesting math problems. At the same time, you can also try to use some math games or math expansion activities to increase your interest in mathematics and stimulate your enthusiasm for learning.
Third, diversified learning methods.
To learn primary school mathematics well, we need to try various learning methods. Different students are suitable for different learning styles, and they can choose the appropriate learning style according to their own characteristics. You can increase your understanding and mastery of knowledge by reading math textbooks, watching math videos and attending math lectures. At the same time, you can organize study groups or discuss and solve difficult problems with your classmates to deepen your impression of mathematics knowledge.
Fourth, summary.
To learn primary school mathematics well, we need to lay a solid foundation of knowledge, cultivate mathematical thinking and try various learning methods. Only by concentrating on learning, paying attention to practice and constantly improving their problem-solving ability and analytical thinking can we achieve excellent results in primary school mathematics learning. Remember, persistence and hard work are the most important things in the process of learning mathematics.
