Fundamental Counting Principle

Hello everyone, I'm super excited about today's video because I talk about the most basic thing that ends up somehow being pretty complex: COUNTING. We will be counting numbers today but not just any numbers, we are covering the fundamental counting principle. You know how sometimes people ask how many numbers are in between 0-100. Your first instinctual answer is 100 but actually, its 101 because we need to remember that 0 is also a number. In most of these types of problems, the main concern is that we need to count accurately. Don't overcount or undercount. Let's jump into the video and check out the different practice problems. The problems get more complex than just asking how many numbers there are. My favorite problem is Practice Problem #5. It tests you on your counting skills but also your understanding of the divisibility rule for 2 and 3.
