What is the logic for finding a reverse of a given number?

First, the remainder of the num divided by 10 is stored in the variable digit . Now, the digit contains the last digit of num , i.e. 4. digit is then added to the variable reversed after multiplying it by 10. Multiplication by 10 adds a new place in the reversed number.

What is the reverse number of 462?

reverse of 462 is 264.

What is reverse order in maths?

When more than one operation acts on a variable in an algebraic equation, apply the reverse of the order of operations to reverse the operations. Here is the order in which you should reverse operations: Reverse addition and subtraction (by subtracting and adding) outside parentheses.

When we reverse the digits of the number 13?

Numbers are (except 13) 24, 35, 46, 57, 68, 79. So. there are 6 other numbers.

Is palindrome a number?

A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16461) that remains the same when its digits are reversed. ... The palindromic primes are 2, 3, 5, 7, 11, 101, 131, 151, ... (sequence A002385 in the OEIS).

How do you reverse a negative number?

For negative numbers, we multiply it by -1 to first make it positive and then apply the same logic, while returning numbers we just multiply it by -1 again to convert the reversed number into negative.
