I figure it's good mental exercise to do as much as NB>>> possible manually... :) BM>> It is, and I'll admit to reaching for the calculator too often: more BM>> out of uncertainty. When going through school they started me with the BM>> "Old Math" and then switch to the "New Math". NB>> When I was in maybe 9th or 10th grade, we had a math teacher that NB>> decided we should have some exposure to the "new math"... but at least NB>> he was careful to keep from confusing us with it... and it became more NB>> of another math tool for us.... BM> As an additional tool probably would have been fine for me but BM> apparently my "new math" was a replacement and undermined what I had BM> learned with the "old math". Anyway, the good news is I generally BM> catch math errors: doing my beginning of the month payments. Either BM> mis-keyed or mis-remembered an entry and when I listed the running BM> total in my credit card journal thought "that's not right". Check: the BM> entry was wrong. It's good to have a mental check running in the background to catch when things don't make sense... ;) BM>> I don't remember what the differences are but do know it confused me BM>> and while I was decent with the Old Math the 'conversion' broke the BM>> rules and I never quite unscrambled them. Can do math manually, and BM>> do, just certain number combinations seem to not quite click. NB>> As I recall, it was adding into the mix things like algebra and NB>> geometry, but not calling them that, just throwing in the concepts NB>> that were supposed to help one understand how adding and subtracting NB>> and multiplying and dividing related to each other.... for some it was NB>> just another layer of MISunderstanding.... What comes to mind for me NB>> is a partly remembered Tom Lehrer song about the "New-ew-ew Math", a NB>> very humorous take on the confusions it generated in young (and not NB>> so young) minds about math.... BM> I must have been one of those confused characters in the song! I did BM> do fairly well in algebra, etc. Didn't take too much 'advanced' math BM> as didn't need to go that deep/'complex'. I eventually went as far as DiffEQ (Differential Equations, but we'd also call them difficult equations) in college after a few quarters of calculus... but then at the time I was a chemistry and then a physics major.... Didn't stay with either one, though.... BM>> OTOH have also used the calculator and realized the answer displayed BM>> doesn't seem right so there is some sort of mental calculating going on. NB>> Which is what my Physics professor Daddy used to refer to as the common NB>> sense factor.... paying attention to whether or not the calculator's NB>> answer made any sense.... did you forget a decimal point, or add one NB>> too early...? Or did you transpose numbers while inputting them...? NB>> I always do it both ways, whichever I do first... and use the one to NB>> check the other... and if they don't agree, do them both again to NB>> find where the glitch is.... :) BM> Your father had a good name for the process! Just because a machine BM> says so, or even someone else, doesn't absolutely mean it's BM> correct/truthful. Exactly... :) BM>> ... Math problems? Call 1-800-[(10x)(13i)2]-[sin(xy)/2.362x] NB>> Speaking of the new-ew-ew math... BM> Do the innermost set first.... And if takes too long just call BM> Directory Assistance! But there's those letters, and that sin(e) of something.... even the calculator can't handle all of that... NB> ... Of people born in 1839, 100% who ate carrots are dead! BM> That seems proof enough carrots are bad for you!! Faulty reasoning, just like one might do with the below.... ;) ttyl neb .... 100% of people who breathe die. --- EzyBlueWave V3.00 01FB001F * Origin: Tiny's BBS - http://www.tinysbbs.com (454:1/452) .
