∙ 7y agoNo because as for example 23 is a Prime number but 32 is a composite number

No, not always. When you reverse a two-digit prime number, the result may or may not be a prime number. It depends on the specific number you are reversing.

The sum of the squares of the digits of 13 is 12 + 32 = 10. The sum of the squares of the digits of this result is 12 + 02 = 1. Because this process results in a 1, this number is a happy number.
No, reversing the order of the digits of a two-digit prime number does not always result in a prime number.
No. For example, reversing 23 gets 32.

the result is always even

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

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.
When multiplying numbers with different numbers of significant digits, the result should have the same number of significant digits as the least precise measurement. Count the number of significant digits in each number, perform the multiplication as usual, and then round the result to the least number of significant digits used in the calculation.
