in section 2 ns& dt, how number are stored in memory it at around 5:53 it says largest number that can be stored in a 8 bit memory is 2^n-1=2^7-1(1 bit is for +ve and -ve) which acc to video is 128 but mathematically it comes out to be 127 how is this possible?
Maybe a Correction
Yes you’re right, I have checked with the mentor too, it’s a typing error and it’s said clearly that it will be 127 but written 128 by mistake.
