(2,3) and (2,5) are the two pairs such that the sum of their elements is a Prime number.

2 + 3 = 5
Prime numbers are numbers that are divisible by themselves and 1. 1 itself is not regarded as a prime number. With the exception of 2, all prime numbers are odd numbers. Applying this gives the following prime numbers less than 25 :- 2,3,5,7,11,13,17,19 and 23.
(13,31)(17,71)(37,73)(79,97)
prime numbers that are less than10 = 2, 3, 5, 7
Only one number can be both even and prime, and that is the number 2.
No. Odd numbers can be greater than, smaller than, or equal to prime numbers.
There are 25 numbers less than 100 that are prime. One is 17.
A single digit prime number
Here are some examples. EX:2,3,7,11,13,19 Prime numbers are numbers that are only divided by themselves and one. So any number that can only be divided by 2 other numbers or less is a prime number!
