LuTze Posted September 6, 2004 Share Posted September 6, 2004 123+456=579, not 512. Are you talking about binary? If so, take the two numbers and do: - 0000 0111 1011 0001 1100 1000 --------------- 0010 0100 0011 Link to comment Share on other sites More sharing options...
Guest hotguy003 Posted September 6, 2004 Share Posted September 6, 2004 the teachers give me this .... but think i lose way to determine in what base? Although the first manned spaceship to land on Mars found no signs of current life, they did find the ruins of an ancient stone all with the following formula engraved on its face: 123 + 456 = 612 Assuming the individual characters all represent the same things as in out notation, how many digits (fingers and thumbs) should the Martians have ( on whatever they used for hands)? Explain how to arrived at your conclusion. HINT you need to deteermine in what base the formula make sense. Link to comment Share on other sites More sharing options...
pulkit Posted September 7, 2004 Share Posted September 7, 2004 The equation cannot have an integral base (123+456=512), hence is invalid. Link to comment Share on other sites More sharing options...
mossoi Posted September 7, 2004 Share Posted September 7, 2004 123 + 456 in base 7 will yield 613 and in base 8, 602. You've given 2 versions of the question, are these correct? Link to comment Share on other sites More sharing options...
pulkit Posted September 7, 2004 Share Posted September 7, 2004 If you change it to 123 + 456 =612 (and not 512 as in the original post) then base = 7 Link to comment Share on other sites More sharing options...

In base 7 answer is 612 not 613 In base 8 answer is 601 not 602 Link to comment Share on other sites More sharing options...
mossoi Posted September 7, 2004 Share Posted September 7, 2004 So it is, forgot to take the 0 into account - oh well, more than ten years since I've done any of this! Link to comment Share on other sites More sharing options...
