What are reversed prime numbers?
Prime numbers that are still prime after their digits are reversed, like (13,31)(17,71)(37,73)(79,97)(107,701)(113,311)
What prime numbers are still prime numbers when their digits are reversed?
Some of them are: 11 13 17 37 and 79
Rational numbers between 3 and 5?
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.
Are prime numbers still prime in non ten digit counting systems?
Yes. Being a prime number has nothing to do with the decimal system.

61 42 56 89

What if both numbers are not prime?
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.
Are negative Numbers prime or Composite?
Negative numbers can be classified as either prime or composite because they still have their absolute value
What is the product of the first 3 prime numbers?
The product of the first three prime numbers (2, 3, and 5) is 30.
Are prime numbers still prime in non ten digit counting systems?

What are the composite numbers between 45 and 60?
Composite numbers are positive integers greater than 1 that have more than two factors. Between 45 and 60, the composite numbers are 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, and 60. These numbers can be divided evenly by numbers other than 1 and themselves, making them composite.
Was the sum of all prime numbers?
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.
Do large numbers give longer number chains?
Most of the time, but large prime numbers still have only two factors.
