But, I still don’t get those letters you say?

What if we had more than nine of something, but not enough to make a base of 16? For example: let’s say that we have eleven items to count. How would we write that amount in base 16?

In base sixteen we use the letters a-f to express amounts greater than nine, but less than sixteen. This is how counting looks in base 16: 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f, When we get past "f" we have one group of 16 and no extra soldiers so we write that number as 10, which just means: one group of 16 and none left over.

Okay, now give this a try:

The number 2f in base 16 is equal to what number in base 10?
