\[1+2+4+16+32+64+128\] i think will do it
anonymous

there is a zero in the 8th place

:P But please show me the steps if you can I would be grateful

In my statement, 10 corresponded to 2 , (in base 2) -_-
anonymous
  • anonymous
work from the right to the left
Christos
  • Christos
That's why rest 8 dont exist :P
Christos
  • Christos
ok satellite ill do it
anonymous
  • anonymous
it is negative number
anonymous
  • anonymous
first invert it
shubhamsrg
  • shubhamsrg
we can talk about 8 if it was base 10 , but when its base 2, talking about 8 is baseless ?

11110111 subtract one 11110110 invert 00001001 now use conversion
anonymous
  • anonymous
should give you -9
Christos
  • Christos
yes indeed it gave me -9 I already had the solution I just needed the steps to reproduce it with other numbers
Christos
  • Christos
=)
anonymous
  • anonymous
it is just subtract one and then invert
Christos
  • Christos
or invert and then add one right?
anonymous
  • anonymous
I think they both work , 1111 invert 0000 add one 0001 1111 subtract one 1110 invert 0001

I am assuming you are in computer architecture class ?

Yea that's right :)
Christos
  • Christos
if it's a sign positive number I don't need to do that stuff right?
anonymous
  • anonymous
no, singed positive number would have leading number =0
