    Despite years of experience, I still enjoy doing computations and
    turning the calculator upside down to spell 80081E5. I suppose your
    inner child never *really* grows up.

    Real life will try to force it to grow up, or try to kill it off, so
    sometimes it is a fight to keep the inner child alive. ;)

    My parents gave all the neices and nephews a CASIO calculator one christmas. A neice showed me hers AND IT HAD A SQUARE ROOT KEY!!!!!!!!!!!!!!!
    My 79 buck 4 banger didn't do square roots so I went to the mall and bought on
    of those.
    Can't remember the Modle Number, couldn't find it in this room, it is probably
    downstairs.

    The fx-82B I mentioned in a previous post has one of those, and it
    apparently doubles as a squaring key. I probably have used that square
    root key some, but not in a long time.

    The other keys... log, sin, cos, and tan... I know what those mean but have
    no idea why I'd ever need them. :D

    Hi, Mike.

    I once asked a maths teacher when his skills had ever come in handy "in real life". He told me that he once had to work out how much corrugated roofing would be needed to cover an outside storage area and so, rather than just measuring the floor and adding a bit, he did some proper triangle geometry.

    "Did it work?"

    "It came out the same as if I'd just measured the floor and added a bit"

    ...I hate having to look for a calculator app on my desktop, and clicking
    buttons with a mouse feels *wrong*.

    If you have a numeric keypad on your keyboard, you can use that. Just make sure your Num Lock is on.

    LOL, so it came out better for him that it probably would have for me, especially if I had tried "proper geometry!" :D

    You just gave me a flashback to when I put some fencing up in our garden. I smugly added in one more post than panels because I'd been taught in school that people often mistakenly think you need the same number of posts as panels then end up a post short.

    When it came to putting the fence up I still found myself one post short because, like a dingbat, I failed to factor in that the fence has a gap in it to access some steps. So instead of n+1 posts I really needed n+2...

    When I called up the fencing supplier to order another post mount she said 'Did you forget to add one?'... 'No, but... yes'.

    When I was out of work and looking for some cheap projects, I bought a
    couple of triangular sun shades to cover an outdoor porch. Both were at
    slight angles canted off of poles of different heights. One layered on
    top of the other, and they were angled so the water would run off the
    edge and miss the porch.

    I measured exactly how big they needed to be and where they needed to be anchored, and nailed it - and finally got to gloat to my son who told me
    he'd *never* use geometry ever again...

    We redid the deck with a higher fence, closed in one of the walls and
    extended the roof to make a nice semi-enclosed deck - but I miss those
    $25 shades.

    Heh, I know the feeling. My Sharp EL-5100 had all that and then some, but I ended up using it mostly for my accounting classes. I didn't care. I had the coolest calc in class.

    That most certainly sounds like a boo-boo that I would make!

    Most of what I use the calculator on my desk for it converting decimal
    to hex and vice versa. Fidonet technology, when passing files back and
    forth, uses the hex representation of the decimal network and node
    number for file names, and figuring out which file goes to who can be
    tricky.

    That has always frustrated me because we dealt with hex at work all the
    time, and the hex values I see on an FTN do *not* equal what we used at
    work. Granted, ours were *usually* EBCDIC but even the ASCII values are
    not "right."

    How did you do it on a calculator? That might be handy to know.

    Although, Synchronet's echocfg utility, where you define nodes, now
    displays the net/node number in hex. Handy!

    Yes it does.

    my favorite calc. is a Sharp EL-501W Scientific Calculator
    It has all of those keys on it

    I will occasionally grab the TI Math on keys book when I do fancy calculations. Ed

    Ready ng Your post to Mike had me to grab the calc to see what 9 times $F is. &87 or 135 decimal.
    .

    Back at work there was a Remote Control station that was coded in Octal.
    I was just learningabout Hexadecimal and knowing that helped me figure out that 3 Bit Code.
    While I still was working, a friend I taked to on the telepone had got hiredas a Electronic Repairman for a Company, and he was telling me about having a problem understandng Octal that the company's Service Manuals used.
    I helped him a ittle by telling him about how I adjusted to learnng about Octal.

    I like HEX better than OCTAL , but having a calc that has options for them (which I wish was available in the 1970's) makes doing the conversion much much easier.
    Yes, I had to use pen and paper learning Octal.

    I memorized the Decimal Table on the back of Double Q notebook (12 X 12) in school but You outdid me by learnng the HEX Multiple Table. NO, I ain't gonna try learning that.
