What are some examples of symmetrical prime numbers?
11
What is a prime number example?
A prime number is a positive integer that only has two factors. 2, 3, 5 and 7 are examples of prime numbers.
What prime numbers when reversed are also prime?
Prime numbers that remain prime when their digits are reversed are called emirps. Some examples of emirps include 13 (31), 17 (71), 31 (13), and 37 (73). These numbers are interesting because both the original number and its reverse are prime numbers.
Are their more prime numbers than normal numbers?
No, there are more normal numbers than prime numbers. Since 2, 3, 5, 13, and 19 are some examples of prime numbers, those only seem to be a few. Remember, numbers can stretch as far as someone wants, so 1,000 isn't a prime number, since you can have 250 and 4 to multiply into it, and 250 and 4 aren't prime numbers. Since the number scale can go on forever, there are more real numbers than prime numbers.
Are all even numbers the sum of two prime numbers?
No. Not even close. Examples: 4+4=8 8+8=16 16+16=32 . . .4, 8, and 16 are not prime numbers.
