312 PointsHow Binary Works?
For example. 00000111 I entered 4 because I counted it from the right to left including the zero before the 1.
Edit: I edited the title of question so its easier to find in google - Konrad

28,888 PointsHi Sammy,
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

2,435 PointsI agree lol watched so many yt videos and they are soo bad.
What do you do with that 7 ? convert it itnot hex and then letter ? and how do you count e.g :
000030111000004111000350011440001113011410000011111
Does it include the 8 rule that goes from right and when u counted 8 , u start from 1 and count to 8 again?

351 PointsNow I don't feel so bad for asking the question! LOL
Actually, the reason why I asked is that I know how to do it, I am not very good at explaining it to my students. So, I thought if I asked the question the way I did, you would give me the simplest explanation you could. It worked!
My Grade 3 students started giving me the answers before I even completed the explanation! (i.e., students are smarter than their teacher . . . .)

28,888 PointsKonrad,
Well it really depends on what you're doing.
As for how you convert that long string, the simple answer is... you don't... because binary is simply 1s and 0s. There are no 3s or 4s or any other number. Now if you're asking how to convert a really long number in general, then yes you break everything up into groups of 8. That's why there a "8 bits in 1 byte".
Let's say I have this:
010101000110100101101101
I break that up into groups of eight:
01010100 01101001 01101101
Then I convert them to decimal
84 105 109
Once you convert them to decimal you could look at a Decimal ASCII chart like: http://asciichart.com/
And see that:
84 = T 105 = i 109 = m
Hex is a different beast altogether.

2,435 PointsWow amazing! I just understood how to do it wow. Treehouse should make some bookmarks for some posts that you can see as im at college and i cant bookmark this or put on desktop or do anything apart from searching it back again.
Thank you .

2,435 PointsOne thing, if we look here there are 6 digits, so does it apply the same terminology? but we start from 6..5..4..3..2..1.. ? and convert it ?

28,888 PointsKonrad,
In terms of the link you submitted with the number being 10000 yes, you can just consider there being two zones in the front. 10000 would be 16.
