Hi there! Let's take a look at the binary number 1101 for example. I'm going to be using ^ to denote "to the power of". For example 4^2 = 16. The far right side will be 2^0 and we count up from there.

2^3 = 8

2^2 = 4

2^0 = 1

That gives us a total of 13. We only really need to pay attention to where the ones are as any 0 will only result in a 0 and not affect the total. Hope this helps! :sparkles:
