Column Multiplication 乘法竖式
32 x 18 =
We start by stacking the numbers.
咱们先把数摞着放。
It is easier to put the *** aller number on the bottom.
把小的数放底下更好算。
Make sure to line up the ones and tens.
个位、十位要对齐。
These are our factors,
这些叫乘数word *** 数学竖式,
and our answer is the product.
结果叫乘积。
Put a little x for 'times' to the left of the bottom number.
在底下的数左边写一个x,表示“乘”。
First, we multiply the top ones number by the ones column of the bottom number,
首先,我们用上面那个数的个位乘以底下那个数的个位。
2 x 8 = 16,
so we put 6 under the line,
所以我们把6写在线下面,
and write a little 1 to the right of this 1.
然后在1的右边写一个小1。
Next, 3 x 8 = 24,
and plus the 1 that's carried over, equals 25.
然后加上进上来的1,等于25。
Write 2 in the hundreds place and 5 in the tens place.
把2写在百位上,5写在十位上。
Then, we'll multiply the top number by the tens of the bottom number,
然后,我们用上面这个数乘以底下这个数的十位。
1 x 2 = 2,
so put 2 in the tens place under the first product.
所以把2写在第一个积下面的十位上。
1 x 3 = 3,
so put 3 in the hundreds place.
所以把3写在百位上。
Next, add our two products together:
然后,把两个积加起来:
256 + 320 = 576.
The answer is 576.
答案是576。
