all in vain!
i'm the proud owner of a Sharp EL-506R; and i love it!
i've used it for basic arithmetic but I need some help to unlock the
keys i'm really interested in right now, as a beginner doing some
algebra, linear equations, quadratic binomials etc
(can't work out how to activate the blue keys if that makes sense to
could someone recommend where i might get help online?
(the fold-out sheet of instructions i got with calc. is not much help,
as it jumps right in using symbols and language that i don't
thx for any help,
