Prime numbers that are still prime after their digits are reversed, like (13,31)(17,71)(37,73)(79,97)(107,701)(113,311)
Some of them are: 11 13 17 37 and 79
There are infinitely many of them.Some of them are given by:All numbers of the form 3n+1/n for n ∈ the prime numbers are rational numbers between 3 & 4, and as there are an infinite number of prime numbers, there are an infinite number of these.All numbers of the form 4n+1/n for n ∈ the prime numbers are rational numbers between 4 & 5, and as there are an infinite number of prime numbers, there are an infinite number of these.There are still more than the infinitely many given above.
Yes. Being a prime number has nothing to do with the decimal system.

You can still do math if two numbers in a equation are not prime for example 4+9 can be solved even though they are not prime, but composite numbers.
Negative numbers can be classified as either prime or composite because they still have their absolute value
The product of the first three prime numbers (2, 3, and 5) is 30.

Prime numbers with hundreds of digits have been found, but there are still more to come that haven't been found yet. It's not possible to add up all the prime numbers, because nobody knows what they all are yet. Since there is no last prime number (this was proved 2000 years ago by Euclid), the sum of all prime numbers is infinite.
Most of the time, but large prime numbers still have only two factors.
The largest known prime number is 17,425,170, although technically, there is no largest possible prime number. To this day, mathematicians are still searching for higher prime numbers.
