How many prime numbers are there from 1 to 100?

I'm curious to know, how many prime numbers can we find within the range of 1 to 100? It's a question that's often posed in mathematics, particularly when delving into the world of numbers and their properties. Prime numbers, as we know, are those numbers greater than 1 that have no divisors other than 1 and themselves. So, when we consider the numbers from 1 to 100, how many of them fit this definition? Is there a pattern or a method to identify them all efficiently? Let's explore and find out the answer together.
