Math problems are not boring. There are many interesting math problems related to our life. I have sorted out some interesting math problems for primary school students, so let your math be full of color quickly!
1September 28th, 982, a radio commentator mentioned in the program that it would be an interesting digital palindrome if the date of the day was shortened to 28.9.82. Susan, who likes to get to the bottom of the matter, also wants to study the distribution of palindromes after listening to the program. She quickly concluded that some years have more palindromes than others, and she also found the two closest palindromes in this century. Do you know what Susan's research results are?
Analysis and solutions
In 1982, except for 10 and 12, the palindrome date will be formed on the 28th of each month, such as 28.6.82. In addition,1February 8, 982 (2.8.82) is also a palindrome date, so 1982 * * has1palindrome date. There are few palindromes in the following years, while 1983 only has palindromes from 3.8.83 to 9.8.89, and only one day in August will form palindromes every year.
By juxtaposing double-digit dates with single-digit dates in the same month or adjacent months, it is easier to find two similar palindrome dates.
For example, the intervals between 1.2.2 1 and 12.2.2 1 and between 22. 1.22 and 2.2.22 are1. So a closer date should be:
29.8.92 and 2.9.92
The interval is only four days.
