Computer Basics 4: Decoding a Binary Number

In this video, we decode a number written in binary notation.
Let's talk about the binary numeral system, also known as a bunch of 1's and 0's over and over again.
We're going to start by labeling, staring backwards, how many numbers there are.
(In this video there are 7, but we start at 0, so we only get up to 6.) Pretty straightforward.
The next step is to take 2 to the power of whatever place it is, a 2 to the 0, 2 to the 1, all the way up to the largest placeholder.
Then, all we have to do is fill in some mathamatical blanks by completing the exponential 2 problems.
If there is a 1, we keep that number (the two to the exponent solution) and add it to other \1\ or \on\ numbers.
If it's a 0, we disregard it.
In this video, our number adds up to 75.

Wooowww!!! I understood the binary concept in less than 2 minutes.

Do you always use 2 as a base ? (in the third line) like 2^0...2^1.. and so on

[BK-gkfj]

So here two different binary codes can result in the same number?

What I was thought in one month, I understand in in two minutes. 😂

Is it compulsory to take no:2 ?? Or can we choose another number??

binary is like the mother of all numbers ( 0 and 1 )

I see latency when you do that looks like sound. I have a theory similar to this that involves the singularity in 2048. Hi I am new 😅

Wow..Just learnt binary in just less than two minutes 😅, Let me go back to CS50 now

I am confused, shouldn't this be 105?My calculation is:1001011=1 + 0 + 0 + 8 + 0 + 32 + 64 =96
I think you accidentally did the whole thing backwards because it is easier to count binary backwards because of moving from larger numbers to smaller numbers is simplest to think about, but then you accidentally did the whole calculation backwards.

This Is Not binary decoding this Is Some Other Concept

But i am getting different anwser with this method. Before i was using sum of weight meothod...What the hell....
