多位数乘以一位数计算题竖式

英文回答：

When it comes to solving multiplication problems

involving a multi-digit number and a single-digit number,

we typically use the vertical method, also known as long

multiplication. This method allows us to break down the

problem into smaller, more manageable steps.

To illustrate, let's consider the problem of

multiplying a three-digit number, such as 456, by a single-

digit number, say 7. Here's how we would solve it using the

vertical method:

First, we start by multiplying the single-digit number

(7) by the ones place of the three-digit number (6). This

gives us a product of 42. We write down the 2 in the ones

place and carry over the 4 to the next step.

Next, we multiply the single-digit number (7) by the

tens place of the three-digit number (5). This gives us a

product of 35. Since we carried over a 4 from the previous

step, we add it to the product, resulting in 39. We write

down the 9 in the tens place and carry over the 3 to the

next step.

Finally, we multiply the single-digit number (7) by the

hundreds place of the three-digit number (4). This gives us

a product of 28. Again, we add the carried-over 3 from the

previous step, resulting in 31. We write down the 1 in the

hundreds place and the 3 in the thousands place.

To find the final product, we combine the results from

each step. In this case, the product of 456 and 7 is 3192.

Now, let's switch to Chinese to provide a similar

explanation.

中文回答：

对于涉及多位数和一位数的乘法问题，我们通常使用竖式计算

方法，也称为长乘法。这种方法可以将问题分解为更小、更易处理

的步骤。

为了说明这一点，我们来考虑一个将三位数（例如456）乘以

一位数（比如7）的问题。以下是我们使用竖式计算方法解决这个

问题的步骤：

首先，我们从将一位数（7）乘以三位数的个位数（6）开始。

这样得到的积是42。我们将2写在个位上，并将4进位到下一步。

接下来，我们将一位数（7）乘以三位数的十位数（5）。这样

得到的积是35。由于我们从上一步进位了4，我们将其加到积上，

得到39。我们将9写在十位上，并将3进位到下一步。

最后，我们将一位数（7）乘以三位数的百位数（4）。这样得

到的积是28。同样地，我们将上一步进位的3加到积上，得到31。

我们将1写在百位上，将3写在千位上。

为了找到最终的积，我们将每一步的结果相加。在这个例子中，

456乘以7的积是3192。

希望以上的解释能帮助您理解多位数乘以一位数的竖式计算方

法。
