There are 25 of them. Here's an easy way to find them:

-- Write down all the numbers from 1 to 100.

-- Cross out all the even numbers except '2'.

-- Cross out all the numbers with digits that add up to a multiple of '3', except '3'.

-- Cross out all the numbers that end in '5', except '5'.

-- Cross out any others that can be divided evenly by any number other than '1' and themselves.

-- The 25 remaining numbers are the primes you're looking for.

I told you it was easy !
