I don't understand the binary system at all, even after watching the video more than once.

The binary notation doesn't make sense to me.

It is like this
Think of these as placeholders
128 64 32 16 8 4 2 1
  0  0  1  0 1 0 0 0
Then add the values over the 1's = 40
Again
128 64 32 16 8 4 2 1
  0  1  0  0 0 0 0 1
Add the values = 65

Thank you! Maybe Treehouse should use your horizontal format instead of the vertical. Works for me!

You are a wonderful person!

What do you mean "here you go?" I don't see anything that you've sent. I don't understand the video enough to give correct answers in the quiz.

If you look at the link, the Here is in diferent color and bold. Click Here on my previous post.

Hope you see the difference. I know its confusing now, treehouse shouldv keep the previous styling of the links.

Most miscommunication happens when the communicator assumes too much about the person communicated with. ;o)

It's not so much about adding the total number of ones up to get the result. Think of each "1" as kind of an on/off switch and each space represents a number. If the space is "1" then you include the number it represents in your addition.

So each of the 8 spaces mean the following

128 - 64 - 32 - 16 - 8 - 4 - 2 - 1

So if you have a binary number like 00000111 you could think of it like:

off - off - off - off - off - on - on - on, then just take the numbers that are "on" and add them up.

So, 4 + 2 + 1 = 7

00000111 = 7
