No. For example, reversing 23 gets 32.

As a result of the rule that you use the definition of the term - such as significant digits - when finding them for a number.

Your question is incomplete. Adding an even number with an odd number will always result in an odd number. Multiplying an even number with an odd number will always result in an even number.

A rational number is always the result of dividing an integer when the divisor is nonzero.

an odd numberSubtracting an odd number from an even number will always result in an odd number.

As a result of the rule that you use the definition of the term - such as significant digits - when finding them for a number.

To determine if a number is a palindrome, simply reverse all the digits, then check if the reversed number is equal to the original number. To reverse the digits of a positive number, num: result = 0 while num > 0 { digit = n % 10 (extract the least significant digit) result = result * 10 (move current result digits one place to the left) result = result + digit (append the new digit) num = num / 10 (move digits one place to the right) } end while return result

It always is a negative number. The result will be the sum of the two digits with a minus sign in front of it, eg, (-4) - (+7) = -4 - 7 = -11.

This follows from the property that the set of integers is closed under addition. This means that any two integers, when added together, must always result in a whole number.

A positive number multiplied by a negative number will always result in a negative number.
