The process of flipping numbers is formally known as “inversion”. This refers to a mathematical transformation in which a number, or a set of numbers, are replaced with an opposite number, or set of numbers, that bear a specific relationship to the original.
For example, if a number is divided into its inverse, one number will be the inverse of the other. Common examples of inversion include taking the square root of a number or reversing the sequence of digits in a number.
Inversion can also be used to describe the process of reversing the sign of a number, which is often expressed as multiplying a number by -1.

What is a palindrome of 89?
A palindrome of 89 is 98. A palindrome is a word, phrase, or number that reads the same backwards as forwards. In the case of 89 and 98, both numbers contain the same digits, just in reverse order. This is known as a numeric palindrome.
In addition to 89 and 98, other examples of numeric palindromes are 11, 121, and 7227.
What are the 3 step palindrome numbers?
The 3-step palindrome numbers are those numbers that are symmetrical from left to right, such as 101, 111, 121, etc. To form these numbers, you need to arrange the digits in three steps. The first step is to write the number starting from left to right as is; the second step is to invert the digits on the second half of the number; and the third step is to write the third half of the number below the second half.
For instance, to get the 101 palindrome number, you would write the number 1-0-1. You invert the numbers on the second half to get 0-1, and then write this number below the first half of the number. You would then get the palindrome number of 101.
You can continue this process for numbers of any length as long as it is divisible by three.
What are 3 examples of a palindrome?
Palindromes are words, phrases, or sequences that read the same forwards or backwards. Here are three examples of palindromes:
1. “Racecar” – this word is the same when read forwards or backwards.
2. “Able was I ere I saw Elba” – this phrase was said to have been uttered by Napoleon during his exile to the island of Elba in 1814.
3. “Rats live on no evil star” – this phrase makes sense when read in both directions.
What is the most famous palindrome?
The most famous palindrome is probably “Able was I ere I saw Elba,” an altered version of the phrase attributed to Napoleon Bonaparte when contemplating exile on the island of Elba. The phrase is commonly rendered as “Able was I ere I saw Elba,” though Napoleon did not actually say this exact phrase, and was likely paraphrased and altered later by various authors who read about his exile.
This palindrome is truly remarkable because not only is it grammatically correct, but the fact that it says the same thing forwards and backwards is also a testament to Napoleon’s illustrious reputation even after his exile.
What are palindrome numbers give 5 examples each?
A palindrome number is a number that reads the same both ways. For example, “121” is a palindrome number, as is “999”, “323”, and “11”.
Some more examples of palindrome numbers are:
101, 202, 505, 606, 707
808, 909, 1001, 2002, 3003
Is 11111 a palindrome?
Yes, 11111 is a palindrome. A palindrome is a word or sequence of characters that reads the same backward as forward. This makes 11111 a perfect example of a palindrome, since the sequence of characters, “11111,” reads the same when reversed.
Palindromes are often interpreted as a type of code—in this case, the numbers “11111” could represent a certain message or concept when read forwards or backwards.
How many 7 letter palindromes are there?
As the number of 7 letter palindromes depends on which language you are using and how liberal you are with what constitutes a valid palindrome. However, if you are only considering English and are willing to accept words with a modified spelling or words that use phonetic pronunciation, then the possible number of 7 letter palindromes is approximately 2,684.
This includes common ones like “level” and “kayak”, but also less common ones like “rotator” and “deedeed”.
