Early Math on Khan Academy: Math begins with counting. It’s the most important skill we learn in our early years and becomes the foundation for all other math concepts. Once we can count, we can add, subtract, and measure the world around us. Shortly thereafter, we can learn about place values, plots, graphs, time, money, and shapes. These early math skills are presented in this subject’s tutorials in a straightforward, understandable, and (dare we say it) fun way!

Actually quite useful coming from an english person wanting to learn about us currency

I don’t understand. Why don’t these coins have an prominent Arabic number on the coin? (e.g., 25, 10, 5, 1) Why doesn’t coin size correlate with denomination?
Penny = 1 cent
Nickle = 5 cents
Dime = 10 cents
Quarter = 25 cents

Can’t you combine all your early math videos into one instead of seeing 5 videos all 3 minutes long when looking at my subscriptions? I love your content on linear algebra and that wasn’t split into 3 minute segments. This is bombardment when looking to see new videos from subscriptions. Guess I will just bookmark this instead of subscirbing and hope I don’t reinstall my browser forgetting to backup bookmarks.

I don’t understand why learning unmarked american coinage is tested here. It is like asking someone to calculated the value of a unmarked circle then tell them they are incorrect.
