Binary

Hey! Sure binary isn't the most useful thing ever, but it's not a bad thing.

OK. First, you should see the pattern in ASCII and number binary that it always 00000000 00000001 00000010 00000011 00000100 etc.. see it? Look closely. 01 10 11 100 101 110 111 see? if you did then here's the next step: memorizing the pattern. Once you can see and memorize the pattern, then read this. 1 = 01; 2 = 10; 3 = 11; 4 = 100 etc. Try filling out the rest.





COUNTING IN BINARY W/ FINGERS



A lot easier than memorizing. Look at pic. Thumb is one, first finger is two, middle is four, ring is 8, and pinky is 16. Note that the pattern is doubling. For a number (Let's say 7) you would add up with your fingers the numbers you have. 1, 2 and 4 = 7. You would put up your thumb first and middle fingers. Now for translating. all fingers down are zeroes, and up are ones. so seven would be 00111 in 5-bit binary. (the 'bit' is how many fingers you use) In 10-bit binary, you would use two hands from RIGHT TO LEFT: 1, 2 ,4, 8, 16, 32, 64, 128, 256, and 512. More bits, more numbers.
