How to memorize multiplication mnemonics

Multiplication mnemonic fast memorization method is as follows:

Multiplication mnemonic is a very basic and important part of learning math, it can help us quickly calculate a large number of multiplication operations. Traditional multiplication mnemonics need to be mastered by rote memorization, but in practice, this kind of memorization may be forgotten, misremembered and other problems. Therefore, this article will introduce you to a simpler and more efficient method of rapid memorization of multiplication mnemonics, which can easily cope with various multiplication calculations.

1, the basic rules of memory

Multiplication mnemonics have some basic laws that can help us quickly memorize, for example: any number and 0 multiplication results in 0. Any number and 1 multiplication results in itself; any number and 10 multiplication, just in the number of the number of complementary to the back of a 0 can be.

2,Double-digit multiplication memorization

First, multiply the tens place and the ones place of two numbers according to the multiplication table form to get a result. Then, add the tens and digits of the two numbers to get a rounded number. Finally, the two results above are combined together to give the final multiplication calculation.

For example, to multiply 23 by 45: first multiply 3 by 5 to get 15, then add 3 to 4 to get 7, and finally combine 15 and 7 to get the final result of 315. In this way, we can multiply double-digit numbers quickly and accurately.

3, three-digit and above multiplication memorization

First of all, the larger number according to the number of digits into a number of segments, each segment contains connected digits. For example, if you want to multiply 456 by 789, you can divide 789 into three segments, 700 and 80 and 9. Then, multiply the smaller numbers with each segment in turn and add them in place-aligned order. Finally, the results of each segment are added together to get the final multiplication calculation. This method helps us to better handle multiplication calculations with larger digits and reduces the possibility of error.

Summary:

In order to better master the multiplication mnemonic rapid memorization method, we need to practice and consolidate a lot. You can improve the calculation speed and accuracy by practicing exercises and oral math training. In addition, some online tools and exercise generators can be utilized for repeated practice to deepen memory and improve calculation skills.

Multiplication mnemonics is a fundamental part of math learning. By adopting the basic rule memorization method, the two-digit multiplication memorization method, and the three-digit and above multiplication memorization method, we can easily calculate various multiplication operations. Through practice and consolidation, we can gradually master the multiplication mnemonic fast memorization method and be comfortable in practical application.
