sorry grOOvy but I've to disagree you ...
binary isn't just translateable into numbers ... right ... your Binary -> Decimal translations are almost correct
but it also depends if it signed ... if you'Ve got a 3Bit Number code, which is also signed, then '111'[size=-2](2)[/size] = '-1'[size=-2](10)[/size] and '100'[size=-2](2)[/size] = '-4'[size=-2](10)[/size]
... but
the PC only knows 1 and 0 ... how can it show pictucre and movies with just numbers ???
as I said ... binary is EVERYTHING ... text, numbers, pictures, sound ... it's just the way you read it
look an ASCII-Table to know howto translate Binary -> Text
00000000[size=-2](2)[/size] = NULL
00000001[size=-2](2)[/size] - 00011111[size=-2](2)[/size] = System signs
00100000[size=-2](2)[/size] - 01111111[size=-2](2)[/size] = ordinary signs (like '1', 'a' and 'A')
10000000[size=-2](2)[/size] - 11111111[size=-2](2)[/size] = special sings (like 'Ã', 'ü', 'Ã')
I added (2) and (10) to seperate binary from decimal ... I think your maths teacher would go crazy if he sees "111=7" (hundred and eleven is equal to seven) ... then you've to show him that the '111' is binary (ordinary with a lil '2')
