I forgot Grandma’s garage opener code. How many different and unique codes(permutations) are there if the code was 2 digits, 3 digits or 4 digits? How could I find out?
Math Wonders:
Have you ever wondered why a lock is called a combination lock? It really should be a permutation lock!
See in Mathematics we use more precise language:When the order doesn’t matter, it is a Combination. When the order does matter it is a Permutation.
Now Combination Pizza is the right way to use it because it does not matter if you order a ham & pineapple pizza or a pineapple & ham pizza- it will taste the same.
Let’s have a math chat! Leave me a response to this math happening.
