Binary

Lorax

Anyone know of some decent links that explain the basics of binary, (addition, subtraction, division, multiplication, complements, etc)
Thanks

Addition:
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0 + carry 1

Subtraction:
0 - 0 = 0
0 - 1 = 1 (borrow 1)
1 - 0 = 1
1 - 1 = 0

Multiplication:
x * 2^n = Shift all bits n places to the left.

Division:
x / 2^n = Shift all bits n plaves to the right.

Not:
Replace 1's with 0's and vice versa.

Or:
0 or 0 = 0
0 or 1 = 1
1 or 0 = 1
1 or 1 = 1

And:
0 and 0 = 0
0 and 1 = 0
1 and 0 = 0
1 and 1 = 1

XOR:
0 xor 0 = 0
0 xor 1 = 1
1 xor 0 = 1
1 xor 1 = 0

Now try that with qbits.

I don't believe so.

5 qbits (32 possible states) would be the same as 5x32 bits (160 bits to hold all 32 possible states) but would also be able to perform calculations on itself before the answer is given, something you can't do with 160 bits.

The only public known Quantam machine does 5 qbits btw.

if you understand number bases you'll get the whole binary thing easier i'de say - it will also help you understand hexadecimal which is handy to know.
googlize number bases - most colleges have decent tutorials online about how they work.
binary is a number base btw : base 2
