There are 25 prime numbers betwee 0 and 100.
We don't define 1 as a prime, nor 0.

Even numbers except 2 aren't prime. eg: 12. 12/2 = 6
Any number, except 5, that ends with a five is not a prime number. eg: 65, 65/5 = 13
Any number that has the sum of its digits resulting in a number divisible by 3, is not a prime number. eg: 27, 2+7 = 9, 9/3 = 3
So by doing some work, I found out 25 prime numbers between 0 and 100, where 1 is not one of them.

In order to help you work this out the definition of a prime number is a whole number which can only be divided by itself or 1.
The only one who is right is Jantzlee.
91 is not a prime number because it will divide by 7.
