Mirror primes are prime numbers that, when their digits are reversed, form another Prime number. The mirror primes from 1 to 100 are 2, 3, 5, 7, 13, 17, 31, 37, 71, 73, 79, and 97. These numbers are prime in both their original and reversed forms, making them mirror primes within the given range.
Mirror primes are pairs of prime numbers whose digits are reversed. (13,31)(17,71)(37,73)(79,97)
There are 25 primes in 1-100.
There are some patterns, but none that can help you determine, in all cases, whether the number is a prime or not.For example: * All primes except 2 are odd numbers. However, not all odd numbers are primes. * All primes greater than 3 are of the form 6n - 1, or 6n + 1. However, not all numbers of this form are primes.
Symmetrical primes are prime numbers that remain the same when their digits are reversed. The symmetrical primes between 1 and 100 are 2, 3, 5, 7, 11, 101. These numbers are prime because they are only divisible by 1 and themselves, and they are symmetrical because they read the same forwards and backwards.
Euclid proved there are infinite. He said that if there were a finite number of primes, if you multiply all the primes together and then add 1, the result will be a prime. Thus, there are infinite primes.

25 primes.

The only consecutive primes between 1 and 100 are 2 and 3.
Answer: 1, and that is 2?Answer: The only even prime number - nont only between 1 and 100, but among all the prmes - is 2. All higher even numbers are divisible by 2, and therefore not primes.
primes are 1,2,3,5,7,11,13,17,19,23,29,31,41,43,47,53,59,61,67,71,73,79,83,89,91. all others are composites.
