The shortcut for Subsuperscript doesn't work? This error also appears in version 7 on Windows Vista 32bit. The StandardForm for Subscript[a, x]^y looks just like that for Subsuperscript[a, x, y], have you checked its InputForm or tried to Set a value to it? |

The shortcut for Subsuperscript doesn't work? @AlexeiBoulbitch A friend of mine reproduced the error with 8.0.4 on Windows 7 64bit… |

The shortcut for Subsuperscript doesn't work? @Szabolcs My keyboard is the same as yours i.e. I actually type Ctrl+6 and then Ctrl+5. Let me add it to the question. |

How can I display a multigraph with different colored edges? It works fine with version 8 (at least I saw no warnings). Here is the result. |

FindMaxValue specifics The error is caused by MachinePrecision indirectly. Mathematica doesn't give warnings for the mistake caused by MachinePrecision. You can check the document, and for more information, have a look at the links I pasted in this answer. |

FindMaxValue specifics For the last part of the question, it's another story of precision. Try this: t1 = N[Im[ZetaZero[1]], 8]; t2 =
N[Im[ZetaZero[2]], 8]; tmid = (t1 + t2)/2; FindMaxValue[
RiemannSiegelZ[t], {t, tmid, t1, t2}, WorkingPrecision -> 8] |

How can I improve my code for drawing a tree? And you forgot to mention that I only managed to reproduce the leaves. (I really don't know where to store the thick and thin branches ORZ…) |

How to express endogenous variables in terms of exogenous variables? Oh…you're still working on this set of equations? (Related question: mathematica.stackexchange.com/questions/11947/…) |

How to compile the code for generate Pythagorean_triple? I think OP is trying to figure out the mistake in his code…still +1 for the unbelievable fast code :D. |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ @whuber You're right…your two examples have pointed out two defects of my code, which seem not to be easy to fix, I'll add a statement in the answer. |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ @VF1 That's just what I've tried to done in the answer below, but as whuber points out, the solution is still quite incomplete, and I don't know why…ahhhh! Anyway, let me read through all the answers here first! |

How to “Copy as Unicode” from a Notebook? Very useful function! Why not make it available for any code sample? (Now it works only for single expression…) |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ @acl Well, this question is mainly for fun, no deeper intention lies behind it, so, yes, I just want do find all the solutions :). |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ My computer failed to finish running this code, but you've told me the keypoint!! With your hint I've got a way to solve, wait for a moment, I'll post an answer to my own question for the first time :D. BTW, you get how many solutions? I want to check whether my solution is complete or not. |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ Well, I think my solution for $+$, $−$, $×$, $/$ is almost same as Chris', but this method is really hard to extend to the case with $($ and $)$ added in… |

Insert $+$, $-$, $\times$, $/$, $($, $)$ into $123456789$ to make it equal to $100$ Er… this post seems not to contain the solution with ( and ). |
