You take each digit, multiply it by the corresponding power of 16.
So 68 can be written as 6*16^1 + 8*16^0 = 6*16 + 8 = 104.
If the digit is a letter a-f, you substitute decimal 10-15 for it.
Answer:
WHAT SOCIETY?!
Every night we'd still be squatting in caves, hunched around campfires, waiting for the leopards to pick us off....
It's hard to have a society when your means of communication are nearly zero and therefore can't sustain the dialogue necessary to develop the shared values needed to form a society.
Answer:
+, -, *, % are Arithmetical operators because they do math operations
&(AND), | (OR), ! (NOT) are Logic Operators and they do logic gates operations on the bits.
The obvious element for which it can't exist is 0 as a*0=0 independent of modulo
all other elements have an inverse:
1*1≡1
2*3≡6≡1
3*2≡6≡1
4*4≡16≡1
if there are more than a few numbers/guessing is inefficient it can be calculated using the extended euclidean algorithm
