When I worked as a cashier @ age 16 I was nervous about giving the correct change so I used to rely on the register to do the math. However, sometimes I'd hit a wrong key and figure it out, but, I was also worried about making a mistake, etc. However, after some amount of time I did get comfortable with the job and the nerves went away, etc.
Maybe give them a demonstration a few times on counting back change (prior to work). Y'know, where the customer hands you $40 and the bill is $12, so they start counting with the smaller bills from 12: 13, 14, 15.. 20.. 40. Assumes they can count by 1,5,10, 20.

Damnit guys, I'm in HS, and let me tell you, they teach math fvcked up now in the lower grades. idk wtf they think they're doing, but they teach these kids methods of sub/add/multiply/divide that just take WAY to long and make NO sense whatsoever. I never understood why just using the old put the 2 numbers on top of each other and multiply it out doesn't work. They don't teach it anymore!
the school system is slowing everything down for everyone, just for those with IQs less then 60, it's pulling everyone down, and no child left behind made the whole thing 10 times worse.
The point is, there no accountability in schools, you cna do nothing and graduate from hs, get used to it... the US isn't going to be the same anymore.:disgust:
/rant done
(and yes, i can make change without a calculator)

calculators shouldn't be allowed in schools and cash registers shouldn't figure out change.
i'd bet 100% of girls and guys aged 18-21 would be able to do basic addition/subtraction then.

that would be just a band aid. The issue is our public school system maybe some of the worst of the developed nations.

I think it also has to do with how often you use it. I have to admit that I am 24 and most of the way through my Masters program and would be very hard pressed to do most math manually. Sure, I can do basic addition, subtraction, etc. But long division or anything else like that and I would be struggling...simply because I have not used it in YEARS.
Now anyone just out of HS has no excuse.

It is true. My girlfriend, who is currently in the second-ranked Pharmacy school in the nation, needs a calculator to do simple addition and subtraction. She can, however, tell you everything about the mechanism of action for a wide range of pharmaceuticals.

heh I STILL do that all the time. I've retained my hand-math skills for the most part, until I start dealing with complex numbers, like numbers with decimals and whatnot. Large numbers I also use calculators for, simply because of time. I'm also lazy, so calculators are lovely. But why pull one out (I often don't have a calculator in my bookbag unless I know a test is going to have math on it, like for my Astronomy course) when I can do simple A/S/M/D easily with a pen or pencil. I don't even need paper, I'll use a pencil on the desk if I need to.
then again, algebraic math was always my strong point. Getting into geometry and trig is where I start to not do nearly as well.

people forget what the dont use everyday
if you needed to know math to get onto myspace all teenagers would know math
Basic addition is something I used in everyday life. from telling time to figuring out how much my lunch is going to cost me. Addition and subtraction are at the cornerstone of just about every activity. This is a skill I mastered in the first grade.

Some time last year, my daughter was doing science homework, and I saw her using a calculator.
I asked her why. She said the teacher said to go ahead and use one, since it was science homework.
I told her to go ahead and do the math herself, then she could check it with the calculator when she was done.

18-21 is -3, you dont seriously expect a -3 year old to do basic addition divided by subtraction w divided by o calculator... do you?!
They should stop calling it math and call it using a calculator 101. Just be honest about not teaching math.
One would assume since she is in the #2 rated Pharmacy school that she is not stupid, so perhaps being able to do simple math isn't the great litmus test of intelligence that people here seem to be indicating.
And why should she need to know? Does you know how to skin a deer? I bet you just say "leave me alone! Leave me and my industrial packaged meat alone!" There are a ton of skills that were absolutely vital to life as recently as 75 years ago but which don't mean squat now. Can you saddle you own horse for example?
I can believe it. There was this person that tried to do a tip while me and a few friends were out. 15%, normal tip.
"Don't take your phone out," I said, "there's a faster way to do it. What's 10% of your bill?"
Of course she doesn't know, and she gave up after I tried explaining it to her and then did it all myself before she even unflipped her phone. Too bad she wasn't cute or exciting, either.
