    Yeah, UFOs are one of those things that you just can't believe until you see one for yourself.

    "You idiot. We're the People's Front of Judea!"

    Splitter!

    And to bed with a smile. Thanks There's been little to smile about in the last year (and no sign of that improving in the year to come).

    Lone voice: "I'm not."

    almost exactly three but it's a very small swimming pool

    Damn damn and thrice damn - I calculated it to the length of the sides and forgot to make allowance for the corners.

    With such a small pool that makes a significant difference and takes it up to 4 47/81 cubic yards

    Maths has a vocabulary and a grammar - BODMAS, mentioned above, is central to the grammar part. That and the vocabulary, made of the essential equations and numeracy, have been ditched in favor of "imaginative thinking and creative problem solving" when they really must be precursors. Without the grammar and vocabulary there's no point trying to think through any of the imaginative thoughts or creative problems because the only tools to hand are blunt inappropriate toys.

    I do think there's an exception to this. Anyone who can get meaningful clear information out of Mathematica using real-world data has got the job, regardless of what the job is.

    It’s normal. You must provoke. You must insult the belief of all monotheists. You must make fun of the belief of all monotheists.

    Hey you guys, what is your mnemonic for "BODMUS?"

    Because our similar rule is "PEMDAS."

    "Please excuse my dear Aunt Sally." for:

    Parentheses
    Exponents
    Multiply
    Divide
    Add
    Subtract

    Or "Purple elephants must dine at sunset," "Pink Emus must dance at sunrise" "Please electrocute mu dirty, aggravating sister" or even "Please eliminate my disgusting arithmetic subject." as my students have created in the past.

    BODMAS - Brackets, Order, Divide and Multiply, Add and Subtract.

    I don't think I use any sentence-mnemonic for anything, it's easier just to recall the thing itself.

    So "Order" is your word for "Exponents?" Fascinating.
