There is only one Prime number which is even and that is 2 and prime number rule applies for only positive numbers. so
we have
2000 and u can arrange 2000 in 4! ways but digit there are 3 '0's
so the answer is 4!/3! and there 4 such numbers less than 10000 which ad upto 2.
10000.......1(including 198 zero between 1s)
Prime numbers go on forever.
11 is the only prime number with identical digits. After 11 all numbers with identical digits can be divided by atleast 11 or 3.
If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)

infintate as numbers do not stop, so you can keep adding digits at the end of the negative number.
solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.
There are 1229 prime numbers that are less than 10000.
Prime numbers are infinite.
It is: 73 of which 7 and 3 are both prime numbers
