Question

Mathematics

Hi guys. Here's a question:
In the binary system, the largest 2-digit number is 11
The largest 3-digit number is 111
The largest 4-digit number is 1111
What is the largest 8-digit number?
I know how the sums above add up, but I can't figure out how to add from 8 digits?

Answer 1

What is the largest number with 8 digits?

11111111(2) = 255(10)
In the same way.

Answer 2

It is possible that the first bit is the sign of the number. Here either 11111111 or 01111111

Answer 3

What exactly is not clear from the words "binary system" and "eight digits"?
It is clear that the largest number is eight ones.
In a standard Windows calculator, type 8 units in binary mode and convert to decimal, get 255.
The dimension of a byte. 255=xFF=b11111111

Answer 4

Combines are not sharpened for this, there should be a 255 digit, but if the digits of the bits are digital, then you will succeed
