1, a×b+c=a×b+a×c, where a, b and c are arbitrary real numbers or algebraic expressions. The intuitive meaning of this law is that when we assign a number (such as A) to the sum of two or more numbers (such as B and C), the product obtained is equal to this number multiplied by each number and then summed.
2. The laws of multiplication and distribution have many applications in mathematics. For example, it can be used to solve some problems in real life, such as calculating the number of combinations or solving some geometric problems. In addition, multiplication and division are also the basis of many complex mathematical operations, such as calculus, linear algebra, probability theory and so on.
3. The multiplication and division method is not only applicable to real numbers and algebraic expressions, but also to mathematical objects such as matrices and vectors. For example, in matrix operation, the multiplication and distribution law can be expressed as: A× B+C = AB+A× C, where a, b and c are arbitrary matrices. Multiplication and division is a basic mathematical tool, which is widely used in mathematics and science.
Learn the skills of multiplication
1, recite multiplication formula: multiplication formula is the basis of learning multiplication, which needs repeated practice and memory until you can recite it skillfully. Understand the meaning of multiplication: multiplication is a basic mathematical operation that represents the sum of two or more numbers. When learning multiplication, we need to understand the meaning of multiplication in order to better understand the essence of multiplication.
2. Master the distribution law of multiplication: the distribution law of multiplication is an important skill to learn multiplication. It can assign a number to the sum of two or more numbers, thus simplifying the calculation. Master simple algorithms: when calculating multiplication, we can use some simple algorithms, such as associative law and commutative law, which can help us calculate the result faster.
3, more practice: learning multiplication requires a lot of practice, only through continuous practice, can improve their computing power and reaction speed. Pay attention to error analysis: when learning multiplication, you need to pay attention to error analysis, find out the reasons for your own calculation errors and improve them. Good study habits are the basis of learning multiplication. You need to listen carefully, take notes, think more and ask more questions.
