Perhaps check-in every day to do questions and enjoy the fun of thinking!
This is fun math to accompany you on the 1750th day to check in and do the questions!
How to view the answer
There are often questions about how to view the answer, so I will answer it here.
answers will be announced in the punch-in applet at 22:00 every night. Please enter the applet to view the answers after 22:00. Of course, you can also pay 1 yuan to read the answer in advance.
Note ①: In order not to affect your thinking by other questions, we have enabled the anti-cheating mode. Only by submitting a check-in can we see the answers and the answers of other questions.
Note ②: When you enter the mini program, you see the clock in question on the date of the day. If you need to view the previous check-in questions (or answers), you can locate the punch in question by selecting the date at the top of the check-in applet.
Note③: If you need to recommend a question, please add Teacher Ziyu’s WeChat: zalyork, and indicate [Recommended Questions]. The recommended question is moderately difficult and more interesting. Try not to involve advanced mathematics knowledge.
