Welcome to learning multiplication! Multiplication is a mathematical operation that serves as a shortcut for repeated addition. When we see three times four, it means we add the number three, four times. Let's visualize this with dots to make it clear.
Now let's learn about the multiplication table. The multiplication table is a chart that helps us memorize basic multiplication facts. Let's start with the two times table. Two times one equals two, two times two equals four, two times three equals six, and so on. Learning these tables by heart will make multiplication much faster and easier.
When we multiply larger numbers, we use vertical multiplication. Let's solve twenty-three times four. First, we multiply three times four which equals twelve. Then we multiply twenty times four which equals eighty. Finally, we add twelve plus eighty to get ninety-two. This method helps us organize our work clearly.
乘法在实际生活中非常有用。让我们解决一个实际问题。如果一个盒子里有六个苹果，那么四个盒子里有多少个苹果？我们可以用乘法来解决这个问题。六乘以四等于二十四。所以总共有二十四个苹果。这展示了乘法如何帮助我们快速计算成组的物品数量。
To summarize what we have learned about multiplication: First, multiplication is a shortcut for repeated addition. Second, memorizing multiplication tables helps us calculate faster. Third, we can use the vertical method for larger numbers. Fourth, multiplication helps solve real-world problems. Finally, regular practice builds confidence and skill in mathematics.
