|LESSON 1:02:02|
Binary has a kind of table used to convert it to decimal. It's like this:
_________
|16|8|4|2|1|
-------------
| 1 |0|1|1|0|
-------------
Very crappy, but the best I can show you.
I just typed in the binary number 10110, as you can see, and it shows the numbers 1, 2, 4, 8 and 16. So what do you think we are going to be doing to convert binary to decimal?
Well, the 1s mean it is true, and the 0s mean it is false. Let's just say that.
Lets go to the numbers above. 4, 2 and 16 are true. So we add them and we get...22!
So, 22 in base 2 is 10110, and 10110 in base 10 is 22.
