The digits in binary numbers represent powers of two.
00:06
So to write decimal numbers of binary number, first we decompose it into sums of powers of two.
00:16
So three would be two to the one plus two to the zero.
00:29
That's two plus one equals three.
00:33
So this is a one in the first digit, place, that's 2 to the 0, and a 1 in the second digit place, that's 2 to the 1.
00:46
That's equal to 3 in binary.
00:50
This digit is the least significant bit, and this digit is the most significant bit.
00:56
The least significant bit is the last digit, the most significant bit is the first digit.
01:01
Then we can write 10, which would be, you can think of it as like sums of powers of 2.
01:15
So 8 plus 2.
01:22
8 is 2 to 3, and 2 is 2.
01:29
Right, so that would be 1, 0, because there's no 2 to the 2.
01:35
1, 0.
01:42
So this represents 10 in binary.
01:48
This is decimal.
01:50
This is binary.
01:52
Again, the last digit is the least significant bit...
