Thank you for the encouragement there.
EDIT: IF you don't have confidence, watch this.
So, I picked the first file, which is 00000000, which is a binary code. Now, here is how to understand what it is in Hex.
First, split each column into 4, for example, 00000000 would be 0000 0000. Now, to turn them into Hex. The thing is 0000 always equals 0 in hex, so simply 0000 0000 would just be 00 in Hex form(For other types, this would be different.
So, now onto the first hex of the file. So, to I took a look at the binary of the first hex of the file. Now, look at it this way. The binary of the first hex was 00000010. Now, to convert it into Hex, I would have to split it in half(since it is 8, and half of 8 is 4), so it would look like 0000 0010. Now, of course 0000 is 0. Now, to look at 0010. 0010 in Hex would simply be 02. Now, if you were to group both sides together, it would be 002, but a hex can only be two digits, so since the 0 at the beginning is not needed, it would be 02, which is the first hex.
