Inappropriate. Most retail sales cash registers require
exact monies provided by the buyer/purchaser. This
includes McDonalds. Whether the change is known or not by
the person operating the cash register, the change
provided will be as noted by the register, not the
operator's estimation of such. If the register fails
during the transaction, the manager will make such change.
Usually under assist of paperizing arithmetic. After
that, the doors close until power is restored.
Current public schools in general do not promote the
"drudgery" of repetive arithmetic problems and their
solutions. So promoting managed solutions at the learned
level. Rather, shortcuts to such solutions. Its
certainly not the fault of the students/"kids". Just the
environment that is forced upon them.
You are so right when you say that public school do not
promote the process of learning. I teach people from ages
16 to as old as 73 in the Emergency Medical Technician
program in my home state. Yesterday, I evaluated another
instructor's course and the poor math skills of the younger
students reared it's ugly head again. The student simply
counted to 39 and multiplied by two in his head and came out
with a pulse rate of 79. It is impossible to multiply a
whole number (even if it is an odd number like 39) and come
out with an odd number. That should have told the student
that his answer was wrong. That concept was totally lost on
the prospective Emergency Medical Technician who may some
day work on you or me. It is NOT the responsibility of an
EMT instructor to teach the student how to add or multiply
two numbers together, it is the primary school's
responsibility which has failed, in other words, "the
dumbing down of America."
As for your information about the cash register. It makes
absolutely no difference to a store if there is 10 dimes or
20 nickels in the register as long as there is $1.00 in the
drawer. Where the change comes from and how change is given
does not matter to a store as long as the register amount
compares favorably with the cash drawer amount at the end of
a shift.
