Yeah. I should have said the leading 1 is taking more places, and they are both 5 bits.

which method have you used here exactly?
Author
There was a problem hiding this comment.
I was trying to subtract the power of 2 from 14 to get the binary numbers.
14 - 2^3 = 6
6 - 2^2 = 2
2 = 2^1

| How many bits would you need in order to store the numbers between 0 and 255 inclusive? | ||
| Answer: | ||
| Answer: 2^8 = 256. So, we need 7 bits. b0000000 = 0, and b1111111 = 255 |

Oh. I was 1 bit off. It should take 8 bits to store from 0 to 255.
