人教版一年级数学下册第5单元《人民币简单的计算》重点讲解和例题解析，帮大家快速掌握人民币之间的换算和简单的计算。这部分内容之所以简单，是因为在计算过程当中数字并不是很大，方法也比较的简单，相同单位相加即可。但还是有很多同学对于这部分的学习出现很多问题，其主要原因是对人民币的使用接触较少，在生活当中本事比较常见的问题，但随着孩子们对前壁接触较少，所以在学习的时候并不能理解圆角加减之间的关系和单位之间的换算，这无疑给同学们学习的时候带来了很大的困扰。
This part is simple because the numbers are not very large in the calculation process, the methods are relatively simple, and the same units are simple enough to add together. But there are still a lot of students who have problems with this part of their studies, mainly because they have less contact with the renminbi and more common problems in life, but as the children have less contact with the front wall, it is not possible to understand the relationship between the corner plus and the unit.
唐老师今天就带领大家揭秘单位之间的换算，该注意哪些事项？钱币之间的加减该如何进行计算才不会出错。这个部分的核心知识点主要集中在以下两个方面：
Today, Mr. Tang is leading the transition between the secret units. What should we look at? How to calculate the additions and subtractions from the currency does not make any mistakes. The core knowledge of this part is focused on the following two areas:
一、人民币单位间的换算：
Conversion between currency units:
辟谣：灰度创始人并未发文唱空比特币:今日社区中流传一张灰度创始人及前首席执行官Barry Silbert于脸书发文唱空比特币的截图。截图内容显示，Barry Silbert认为若BTC不能站稳45000美元，周末看跌至40000美元，且会看到更多市场波动。而经过查询，脸书上充斥着大量的Barry Silbert虚假账号，发布该内容的账号也并非Barry Silbert本人账号。此外，Barry Silbert推特账号也未发布该内容，其推特上最近一条推文还停留至2月9日。[2021/2/26 17:55:08]
Rumor has come that Barry Silbert, the founder of Greydo, and former Chief Executive Officer Barry Silbert, wrote a screenshot of Bitcoin on Facebook. The screenshot showed that Barry Silbert believed that if BTC could not stand at $45,000, it would fall to $40,000 on weekends and see more market fluctuations. And, after a query, his face was filled with a large number of Barry Silbert false accounts, which were not Barry Silbert’s own account. Moreover, Barry Silbert’s Twitter account did not publish it, and his latest tweet remained on 9 February[2021/2/26 17:55:08].
1.几元几角换算成几角时，先想几元是几十角，再加上几角就是几十几角。
1. When a few cents are converted to a few corners, think first of the fewths is a few dozen, plus a fewths is a few hundredths.
2.几十几角换算成几元几角时，先想几十角是几元，几元和剩下的几角合起来就是几元几角。
2. When a few dozen corners are converted into several parts, think first of a few parts, and a few parts and the remaining parts together are a few parts.
二、人民币的简单计算：
II. Simple calculation of the renminbi:
1.相同单位的数可以直接相加减。
1. The same units may be reduced directly.
分析师：8月份比特币价格超过1万美元的几率为90%:加密货币分析师Timothy Peterson在推特上表示，8月份比特币价格超过1万美元的几率为90%。其分享的一张图表显示，比特币看起来已经越过了最低价格，并在一段时间内持续上涨。
Analysts: The price of Bitcoin exceeded $10,000 in August by 90%: Encrypted Money Analyst Timothy Peterson tweeted that the price of Bitcoin exceeded $10,000 by 90% in August. A chart shared by him shows that Bitcoin appears to have crossed the lowest price and has been rising for some time.
其他分析师观察到的山寨币市场的稳定也是价格即将回升的一个重要信号。山寨币预计不会很快停止上涨，事实上，许多交易员和分析师认为，山寨币季已从本月开始，并可能持续整个月，一直走高，直到比特币出现重大价格波动。比特币在9300美元和9400美元的阻力位遭到强烈的价格拒绝，这是比特币面临的最大挑战之一。（Zycrypto）[2020/7/14]
The stability observed by other analysts is also an important signal that prices are about to rise again. The rise is not expected to stop soon. In fact, many traders and analysts believe that the currency season has begun this month and is likely to continue throughout the month, until Bitcoin has experienced significant price fluctuations. Bitcoin has been strongly rejected at $9,300 and $9,400 in resistance, one of the biggest challenges to Bitcoin. (Zycrypto) [2020/7/14]
2.单位不同时，要先统一单位，再计算。
2. Units shall be unified before they are counted.
动态 | 区块链公司Sparkswap宣布其比特币闪电网络交易所支持美元交易:美国区块链初创公司Sparkswap宣布支持美元，允许用户直接从其Sparkswap闪电钱包购买比特币。此前2019年4月消息，该公司成功完成种子轮融资，打算创建一个基于比特币闪电网络的分散式加密交易所。（The Block）[2019/9/17]
Sparkswap, a block chain company, announced that its Bitcoin Flash Exchange supported dollar transactions: Sparkswap, an American block chain starter, announced its support for the dollar, allowing users to purchase bitcoins directly from its Sparkswap Flash Wallet. Prior to the April 2019 news, the company successfully completed seed rotation financing with the intention of creating a decentralized encrypted exchange based on the Bitcoin Flash Network.

以上两个重要的知识点就是本次课程的核心内容，主要给大家提供了解题的方法和解题的技巧，在实际的操作当中，只要掌握了这两个方面的内容，那么对于提高效率是绝对没有问题的。
These two important points of knowledge are the core content of the course, which provides you with the skills to understand the issues and solve them. In practice, there is absolutely no problem in improving efficiency as long as they are captured.
动态 | 比特币在暗网的交易量在增加 但占比却大幅下降:据彭博社消息，Chainalysis的报告显示，比特币在非法在线交易市场上的应用正在加速，今年有望创下10亿美元的记录。截至目前，今年在暗网交易上交易的比特币就达到了5.15亿美元。而比特币在暗网交易的峰值是2017年的8.72亿美元。报告还显示，比特币在暗网交易品类最大的是药品，比特币也是最受欢迎的加密货币，其次则是门罗币。不过虽然交易量在增加，比特币在整个非法活动中的交易比例仅不到1%，而在2012年这一比例为7%。[2019/7/2]
The volume of Bitcoin dealings on the dark web has increased, but the percentage has declined significantly: according to Bloomberg, the use of Bitcoin in the illicit online trade market is accelerating, with a record of $1 billion expected this year. To date, the amount of Bitcoins traded on the net has reached $515 million. The peak of Bitcoins trading on the dark web was $872 million in 2017. The report also shows that Bitcoin is the largest drug in the dark market category, and Bitcoin is also the most popular encrypted currency, followed by Monroe. But, while the volume of transactions is increasing, the proportion of Bitcoins in the total illicit activity is less than 1 per cent, compared to 7 per cent in 2012.[2019/7/2]
比特币期货:受比特币价格回暖影响，比特币期货价格今日也有部分提升。CBOE比特币期货1月合约今日收盘价格为15760美元，距22日收盘时上涨了470美元，涨幅为3.07%。CME比特币期货1月合约当前价格为15770美元，距22日收盘时上涨了1635美元。[2017/12/27]
Bitcoin futures: The price of bitcoin futures has also increased in part today, as a result of the warming of bitcoin prices. The CBOE futures contract today stands at $157.60, an increase of $470, or 3.07 per cent, from the date of 22 days. The CMEbitco futures contract currently stands at $15.70, an increase of $1635, or 22 days.[2017/12/27]
通过以上的学习，人民币的简单计算主要是通过个相同单位之间的计算来解决问题的，同时还涉及单位之间的换算。这个问题之前我们就在文章当中给大家讲过，如果还不太熟练的同学要进行自我加强练习，把单位换算能做到正向和逆向的互换化简。
Through the above studies, the simple calculation of the renminbi is mainly done by calculating between the same units, but also by referring to the conversion between units. As we have already told you in our articles, if students who are less skilled are going to practice self-reinforcing, the conversion of units can be reduced to positive and reverse swaps.
下面大家就跟随谭老师一起看看在实际的操作当中，这些主要的方法和技巧是否使用，是否能提高大家的计算速度和计算的效率？
Let us now follow Mr. Tan to see if these main methods and techniques are used in practice, and whether they improve the speed and efficiency of calculations.
在学习当中要不断的总结和不断的复习才能让自己的能力变得越来越强大。人民币的简单计算主要的内容归结为以下两个部分，也是其最主要的核心内容。同学们通过以上的学习，对于这部分如果没能很快记住的，一定要做好笔记，以便于以后能随时进行复习。
The simple calculation of the renminbi is divided into the following two parts, which are the most important ones. Through the above studies, students must take notes, if they are not able to remember them quickly, so that they can review them at any time in the future.
最后通过上述的学习，如果还没有掌握人民币简单计算的方法和技巧的同学，可以通过下面这部分练习进行自我的加强和查缺补漏。
Finally, through the above-mentioned studies, students who have not yet acquired the simple methods and techniques of calculating the renminbi can strengthen themselves and identify gaps through the following part of the exercise.
一、填空。
i, empty.
6角+2元3角=元角
6 + $2.3 = dollar
4元5角-2元3角=元角
$4.5-2.3 = dollar corner
5元6角+2元=元角
$5.6 + $2 = dollar
6角+7角=元角
6 + 7 = dollar
二、在○里填上“>”“<”或“=”。
ii. Insert ">" "<" or "=" in the zero.
