Skip to comments.It just doesnít add up: One in three adults canít do simple sums past 100 without a calculator

A fifth of adults are so bad at math that they struggle to perform basic mental arithmetic, a survey has revealed.
More than a third can only manage sums that total less than 100 and have to use a calculator for anything larger.
One in 50 people were stumped by adding or subtracting in their head if the total was more than ten.
And one in three parents believed their childrens ability exceeded their own.

I believe this.
The 47 million people on food stamps can calculate, to the penny, exactly how much they deserve.
I’m still dumbfounded when ADULTS can’t count out correct change without a cash register.
It’s soooooo fun to watch the cashiers in a store when the electricity goes out. Forced the stores to get generators.
They also know how to convert it into drug money.
I don’t. I believe the sumbers are much worse.
I wonder how many people (likely older and with the ability to do simple things like addition and subtraction) still think 1984 and the ideas it covered, aren’t what we are living today. Many used to poo poo the notion.
Hate to say, but my own personal policy is that when a cashier overpays me in change that I say *nothing* anymore and I donate the excess to my church. I used to correct these people in the past and all too often they’d get offended and sometimes even yell at me for insulting their intelligence.
To me the insult was self-evident.
Anyhow, I figure if I say nothing then that person is one step closer to their new job.
And then I go home and teach my kids multiplication tables, short division, and business algebra instead of the mindless ‘theories’ the public schools teach about math anymore.
They are being taught by unionized government employee teachers...Of course they know nothing.
All while the unionized teacher salaries and benefits over the past 20 years has increased dramatically and they demand more $ every single year.
Now we know why a large chunk of the voters think that government spending can be increased and paid for soley by a tax on “the rich.” We are doomed.

That’s why I don’t believe in using computers/calculators in school....learn math the old-fashioned way.
We old engineers sometimes found “trial and error” solutions by the Newton-Raphson method using a bamboo sliderule and our designs proved to be viable. We were slow but well versed in many phases of engineering.
New graduates are specialized and sit in front of a computer and use canned programs to make sophisticated calculations and are sometimes not even sure if their answers are correct.
Teaching Math In 1950
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit?
Teaching Math In 1960
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?
Teaching Math In 1970
A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit?
Teaching Math In 1980
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20 Your assignment: Underline the number 20.
Teaching Math In 1990
A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living?
Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers.)
Teaching Math In 2013
Un ranchero vende una carretera de madera para $100. El cuesto de la produccion era $80. Cuantos tortillas
se puede comprar?
I’ve personally maintained that the first time calculators should be formally introduced is college. A high school graduate should be able to do all the way through calculus without a calculator.
I know. It just doesn't add up to me.
More like Brave New World.
I don’t know..do students still do multiplication, addition tables, and all the other rote learning things we did fifty years ago? I still remember the nun at the blackboard with the pointer and all us kids reciting in unison.
Well in their defense, those machines are sometimes tied to a central store computer for record purposes. On top of that, UPC codes and debit cards cant be used without electricity.
When I got my degree (accounting/finance) we had to learn the math by hand before using calculators. Some of the problems could take 4 pages to solve and sometimes 1 problem was the only question on a test. I have helped some people in the recent past getting the same degree that only learn what buttons to push on the calculator. I’ve read that some of the young finance graduates were responsible for the financial crises, because they never learned the logic that accompanies the formulas.
LOL...Government teachers have severely dumb down the masses for the past 2+ generations...
“Hate to say, but my own personal policy is that when a cashier overpays me in change that I say *nothing* anymore”
I am with you on that. I had someone short me about $10 on my change. I called in the manager and demanded a register count. The register was off by over $100. I got my money and the employee wasn’t there the next day.
She was confused and said "You gave me too much money" and gave me back the dollar bill and the thirty cents.
She processed the transaction giving me $8.73, in exchange for the twenty. I left the money on the counter, then handed her two ones and asked for a ten.
She then looked at me and I could almost see the light bulb click on; "OH!! you wanted a ten back didn't you?"
>>>One in three adults can’t do simple sums past 100 without a calculator<<<
Shocking. One in three? That is almost 25%! :)
Because the article did not clarify it if (the study) is a real test, or it is just a survey. I can't find any link to the study.
Also from the article: “one in three parents believed their childrens ability exceeded their own” - really? are they confusing with the ‘tech savvy’ skill vs. real math/science skill?
Yep. There are three kinds of people: people who understand math and people who don’t.
It;s the impact of technology over time. How many folks can sharpen a wooden pencil with a knife?
We homeschooled, used Saxon Math books, and they always had sections of, what they called, Mental Math. All that meant was no paper and pencil allowed, much less a calculator.
I have a book called Test Your Math IQ (someone gave it to me as a present) and I enjoy solving the problems, just to keep my math skills alive (even though I’ve almost hit the big 60)
it’s good to keep your brain nimble doing word problems and such.
If only the problem were confined to math. The pathetic truth is that people are being given a well rounded education, they are ignorant not just about math but about language, history, government, literature, geography, and many other things. If ignorance had any value we would be rich indeed. The average American soldier in WWII had an eighth grade education and was better educated by far than most recent college graduates.
I have noticed that many people have no “feel” for numbers. If they use a calculator to multiply 41 x 82 and they enter it incorrectly and the answer comes up 336200 they are apt to think that is correct. I learned arithmetic the old way long ago and it instantly flashes in my mind that 40 x 80 is 3200 so there is no way the answer could be six figures long. Terms like 1/4, .25, .250, 0.25, 25% etc. all look the same to me, some people seem to need a calculator and a book to figure out that 1/4 of a pound is the same thing as .25 x 1 pound or 25% of a pound and all are equal to four ounces.
Amazingly enough to me most adults don’t seem to know how many feet are in a land mile, let alone a nautical mile. When I was in grade school I learned that a land mile is 5,280 ft. and a nautical mile is 6000. I could not forget those if I tried, if I ever cannot remember them I will know that I am entering dementia.
I agree. All the educational establishment did was lengthen the time it took to educate the young. They did not teach more information.
If you look at math books, from the early 1900’s, they were teaching, what we teach in grade 12, in the eighth grade.
Your post reminded me of this classic
The Absent-Minded Waiter
I’m just glad it doesn’t have anything to do with pi. I thought pi was some number, but it turns out it’s a book about a tiger eating everyone on a boat.
One in three adults cant do simple sums past 100 without a calculator
“One third of 18 to 24-year-olds admitted having to use them, compared to one in eight people aged over 55.”
And I can bet you when those 55+ year olds were 18 to 24, they sure as heck knew their maths (as they call it), probably two thirds of them...if not more.
Funny, something changed for people younger than 55 years. They didn’t need to learn arithmetic anymore, so the schools were MORE THAN HAPPY to do their part and our last two generations show the results.
Of course some of us aren’t so STUPID as to entrust the public (and, in many cases, private) schools to teach our kids - so we make them learn the right way, but we are STILL a minority, even here at Free Republic.
Anyway, we all know your rationalizations, so don’t bother trying to defend your choices (i.e., my school is different, it is run by good people).
“We old engineers sometimes found trial and error solutions by the Newton-Raphson method using a bamboo sliderule and our designs proved to be viable. We were slow but well versed in many phases of engineering.”
Who the hell are you to talk. What did you guys ever accomplish (other than landing on the moon, building the SR71 in 3 years...and earlier, atomic bombs and Hoover Dam). We’re much better now, we have Solyndra and Enron to speak for our accomplishments.
“I am with you on that. I had someone short me about $10 on my change. I called in the manager and demanded a register count. The register was off by over $100. I got my money and the employee wasnt there the next day.”
Actually, it sounds like the employee was playing the odds there - he (or she) figured that Americans have no capability of doing math in their heads, and was RIGHT the first nine times. But then luck ran out with you.
“Hate to say, but my own personal policy is that when a cashier overpays me in change that I say *nothing* anymore and I donate the excess to my church.”
I hear you, but you are blaming the victim here. It’s not the kid’s fault that he had IDIOT parents that let a bunch of left-wing radicals ‘educate’ him...just so they could keep up with the Jones’s.
This ping list is for the other articles of interest to homeschoolers about education and public school. This can occasionally be a fairly high volume list. Articles pinged to the Another Reason to Homeschool List will be given the keyword of ARTH. (If I remember. If I forget, please feel free to add it yourself)
The main Homeschool Ping List handles the homeschool-specific articles. I hold both the Homeschool Ping List and the Another Reason to Homeschool Ping list. Please freepmail me to let me know if you would like to be added to or removed from either list, or both.
My kids were not permitted to use calculators until 7th grade when they were well into algebra and they needed it for the time saver that it was.
But by then, they KNEW all their multiplication and addition facts and knew how to use them to also subtract and divide.
My criteria for them being allowed to use calculators was that they had to demonstrate to my satisfaction, that they knew their math facts and could use the, all in their heads.
I need a pencil and paper but I can do it. Do it in my head? You must be joking! I was only taught to do it with pencil and paper.
Being a survivor years ago of some fairly high math in a top university and engineering program I have watched and been interested in what schools at all levels teach as to ‘math’. It doesn’t surprise me that much of what was ‘higher math’ then is/can be taken as ordinary useful ‘math’ today. However. I sometimes think that what is being taught today is just ‘programed manipulation’, a la calculator, as opposed to ‘ self logical’ construction. I have a granddaughter going for a business degree who is taking special calculus instruction. I checked the web as to college, regular and others, and found that indeed calculus was being required for a business degree. After some thought I recollected that my courses in calculus did have ‘dollar’ problems,so it is just a matter of changing times and perspectives .
My sister in law is from spain and is a teacher in the US, she will love this when I show it to her.
