Let thirteen symbols, 1,3,5,7,9,2,4,6,8,%,>,<,X, indicate decimal numbers zero through twelve that are in random order; and a place-value system based on the decimal number 13.
Hint: 1 + 3 + 5 + 7 + 9 + 2 + 4 + 6 + 8 + % + > + < + X = 7>
If 7 + 2 = 4 + 5 = <>; 6 + % = < + 3 = <>; X + 1 = 4 + 5 = <>
7 + 2 + 1 + 2 + X = %2
1 + 2 + 3 + 4 + 7 + X + < = X4
1> - 7> = 9>
9> + %. = 7>
9 + < = 4
What are these thirteen symbols, 1,3,5,7,9,2,4,6,8,%,>,<,X, equivalent to in decimal numbers?

Therefore 7> = decimal place-value 78. I was hoping that the reader could figure out the meaning of 7>. (e.g., In the binary system 1+1+1=11) |
Sorry, first time heard place-value system. I was taught in "base number" terminalogy. |
13 进制?7>=78(十进制) =60(13 进制)--- Correct! |
GiveATry: Have you tried this? Somehow, I always get conflict results. Just want to make sure no bug in the question. Cheers |
Yes I have tried. It worked for me. Once again there is a typo (Doesn't the sun rise in the East?). " 9> + %. = 7> Should be 9> + %> = 7> ". If 7 + 2 = 4 + 5 = <>; 6 + % = < + 3 = <>; X + 1 = 4 + 5 = <> 7 + 2 + 1 + 2 + X = %2 1 + 2 + 3 + 4 + 7 + X + < = X4 1> - 7> = 9> 9> + %. = 7> Should be 9> + %> = 7> 9 + < = 4 |
