1. 对于120×20：- 先计算12×2 = 24，然后因为因数末尾共有2个0，所以在24后面添上2个0，结果为2400。
2. 对于130×30：- 计算13×3 = 39，因数末尾共有2个0，就在39后面添2个0，得到3900。
3. 对于140×20：- 先算14×2 = 28，再添2个0，结果是2800。
4. 对于210×30：- 计算21×3 = 63，然后添2个0，为6300。
5. 对于230×20：- 先算23×2 = 46，添2个0后得4600。
6. 对于320×30：- 计算32×3 = 96，添2个0得到9600。
7. 对于310×20：- 先算31×2 = 62，添2个0为6200。
8. 对于410×20：9. 对于420×30：- 先算42×3 = 126，添2个0结果是12600。
10. 对于150×40：- 计算15×4 = 60，添2个0得到6000。

四年级数学三位数乘两位数的计算题篇一：《三位数乘两位数：数学世界的奇妙之旅》嘿，朋友们！今天咱们来聊聊四年级数学里那个让人又爱又恨的三位数乘两位数的计算题。
这可真是个有趣又有点挑战的家伙！就拿325 乘以46 来说吧，这可不简单呐！咱们得一步一步来，就像爬山一样，每一步都得踩稳。
先拿325 乘6，哇塞，这就得用心算啦，5 乘6 等于30，写下0 进3，2 乘6 等于12 加上进的3 就是15，再写下5 进1，3 乘6 等于18 加上进的1 就是19。
这第一步算完，可得小心别出错哟！接下来，再算325 乘40 ，这就像跨大步一样，可不能马虎。
0 乘325 等于0 ，先放着，4 乘5 等于20 ，写下0 进2 ，4 乘2 等于8 加上进的2 就是10 ，写下0 进1 ，4 乘3 等于12 加上进的1 就是13 。
算完这两步，再把它们加起来，这就像是把两段路合成一条大路，得仔仔细细对齐数位。
个位上是0 ，十位上是5 加0 等于5 ，百位上是9 加0 等于9 ，千位上是1 加1 等于2 ，万位上是1 。
最后得出的结果就是14950 。
你说，这像不像一场刺激的冒险？每一步都得小心翼翼，一个数字出错，就全盘皆输啦！我记得有一次，我和同桌一起做这样的计算题。
我做得可认真啦，一笔一划，嘴里还念念有词。
可他呢，急急忙忙，一会儿就说做完了。
我心里还纳闷：“怎么可能这么快？”等老师批改下来，他错了好多，被老师狠狠地批评了一顿。
他耷拉着脑袋，像个泄了气的皮球，嘴里嘟囔着：“我再也不粗心啦！”再想想咱们学数学，不就像搭积木吗？每一道题都是一块积木，只有认真搭好每一块，才能建成牢固又漂亮的“数学大厦”。
三位数乘两位数的计算题就是其中重要的一块积木呀！所以说，朋友们，咱们可别小瞧了这些计算题，认真对待，才能在数学的世界里畅游无阻！我觉得呀，只要咱们用心，多练习，三位数乘两位数的计算题根本难不倒咱们，对吧？篇二：哎呀呀，说起四年级数学里的三位数乘两位数的计算题，那可真是让不少小朋友抓耳挠腮呢！就拿我家小侄子来说吧，有一次我去他家，正瞧见他趴在桌子上，对着一道三位数乘两位数的题目发愁。
四年级三位数乘两位数计算题示例文章篇一：《我的三位数乘两位数计算大冒险》哎呀！最近在数学的世界里，我可经历了一场超级刺激的大冒险——三位数乘两位数的计算！还记得那天，数学老师在黑板上写下了一道三位数乘两位数的题目，“345×23”，然后用她那炯炯有神的眼睛看着我们说：“同学们，谁来挑战一下？”当时，教室里安静得连一根针掉地上都能听见。
我心里那个纠结呀，就像有两个小人在打架。
一个说：“快去试试，怕啥！”另一个却说：“别去，万一做错了多丢人！”最后，勇敢的那个小人胜利了，我举起了手。
我走到黑板前，拿起粉笔，心砰砰直跳，手心里全是汗。
我深吸一口气，开始计算。
先用345 乘3，“一三得三，三四十二，三五十五”，写下1035。
然后再用345 乘20，这可把我难住了，我在心里默默念叨：“二四得八，二五一十，二三十四”，哎呀，不对不对，我又重新算，好不容易算出是6900。
最后把它们相加，1035 + 6900 = 7935 。
我写完后，站在那里，心里七上八下的，等着老师的评判。
老师看了看，微笑着说：“算对啦，很棒！”那一刻，我开心得简直要飞起来，就像一只小鸟终于学会了飞翔！回到座位上，同桌凑过来问我：“你咋这么厉害？快教教我呗！”我得意地说：“这有啥难的，你看，就像搭积木一样，一步一步来，别着急！”可是，这三位数乘两位数的计算可不是每次都这么顺利的。
有一次做作业，有道题是“456×78”，我一开始信心满满，觉得肯定能轻松搞定。
结果算着算着就糊涂了，一会儿忘了进位，一会儿又把数字写错了。
我急得抓耳挠腮，心里像有一团乱麻，“这可咋办呀？”我一边抱怨一边重新算。
妈妈看到我这着急的样子，走过来说：“别着急，宝贝，静下心来。
我们一起来看看。
”妈妈耐心地给我讲解，“你看，先用456 乘8，再用456 乘70，然后把两个结果加起来。
”在妈妈的帮助下，我终于算出了正确答案。
经过这一次次的挑战，我发现三位数乘两位数就像是一个神秘的城堡，虽然有时候会遇到困难，但是只要我勇敢地去探索，认真地去计算，就一定能找到宝藏！现在，我不再害怕三位数乘两位数的计算题啦，反而觉得它们很有趣，就像一个个小谜题等着我去解开。
