I'm not flipping you off, i just counted to 4
19 is the rock and roll symbol
22 is the shocker
Assuming you use your thumb as the first bit
I taught my kids how to do it and for a while they'd tell each other to binary four off
My seven year old did something similar. At least once a day I'd hear 'Dad, Dad, I'm counting to four!' and see the little shit flipping me off and laughing hysterically :D
One hand would be 2**5 = 32 (0 to 31) and two would be 2**10 = 1024 (0 to 1023).
And if you use 3 states per finger (down, half raised and raised), you can have 3**10 = 59049 (0 to 59048).
I don't count to 1024 over often (literally never) so I don't feel the need to go to trinary.
nah, you can have 16+8+4+2+1 = 31 on one hand, and 1024+512+256+128+64+32+16+8+4+2+1=2047 on two hands.
I don't know many people who count like 👍☝️🖕, so you kinda already do. You're just allowing more combinations
The French used to count in base 20 (so that means both hands and both feet), which is why they read 97 as quatre-vingt-dix-sept, ie 4*20+10+7
.
coworker taught me this and it blew my mind. I had previously jokingly used base 2 with my hands, but something like 01001 10010 would be difficult to handle.
If you count finger joints and tips, using your thumb – you can count in hex (base16) on each hand.
Honestly, I count using the four fingers for 1-4, close the fingers and extend thumb for five, then extend each finger again for 6-9.
The right hand counts tens and works the same way. Can count to 100, and it's pretty intuitive. It's like if positional notation was discovered way earlier.
No. We count start at zero because the array already starts with an element of a specific size. Starting at 1 would always skip that initial element.
You could have "empty arrays" in a language if you wanted. The real reason is that you start with an offset of zero as you read an array from memory at hardware level, and so this way address is just "start address + element size * element number".
Because if you convert it back to binary, you have 0x0000 and that is one extra bit you can use instead of limiting your available values.
I literally did this the other day... to be fair, it was a list starting with the number zero.
Fun fact: when learning some instruments (e.g. bowed instruments) you also number the fingers starting from your index (because you don't play with the thumb)
