I Was Told There Would Be No Math

some highlights:

a poll that same year asked, "How many millions are in a trillion?" and 79% of Americans either answered wrong or didn't know.

Most young baby boomers about to enter retirement struggle with basic, real-life financial arithmetic.


Here's an example:
"Let's say you have 200 dollars in a savings account. The account earns 10 percent interest per year. How much would you have in the account at the end of two years?"


Take your time. Feel free to use a calculator. What's your answer?


When asked, 82.2% of those age 51 to 56 couldn't produce the right answer ($242). Of those who answered wrong, about half erred by ignoring that interest accrues on both principal and interest -- compound interest.

    It's quite painful to read that people can't do basic math. More painful that so many didn't know how many millions there are in a trillion.

    "79% of a selected group of Americans either answered wrong or didn't know."

    With such apparent concern of arithmetic and statistics this is poor grammar!

      Even George Bush had a similar problem . . .


      Donald Rumsfeld was giving the president his daily briefing. He concluded by saying: "Yesterday, 3 Brazilian soldiers were killed."

      "OH NO!" the President exclaims. "That's terrible!"

      His staff sat stunned at this display of emotion, nervously watching as the President sits, head in hands.

      Finally, the President looks up and asks, "How many millions is a brazillion?"

          I didn't have a problem with the $242 one, but l have done a business course recently, so l find the Mary bought home 3.5 Apple questions to be relatively easy!


          Most people would probably just Google it!


          I hope that they interviewed people across the board, if it was just factory workers only, then apart from it not being a surprise, the results can be biased?


          But assuming they aren't, then the numbing down of Americans or Australians for that matter is a real concern!


          Maybe the Fluoride, and possible Smart Metres, are creating more stupid people?

            There's definitely a dumbing down - and people think it doesn't matter. After all, they can always "look it up", can't they? I've heard the argument from school kids - they wonder why they need to learn history or geography when they can simply "look it up online" if they ever need to know.

            Technology is amazing and the info stream will only continue to grow. The danger is in allowing a technology info stream to replace a human being's connection with the real world and using his own mind to solve problems.

            You can learn about trees, and forests and wildlife - all of it coming to you via info technology. Nothing, however, can replace the experience of walking through the forest. We need technology to enhance our experiences - not to replace the experience.

              This is a problem. We're constantly barraged with so much information we no longer have time to actually think about it, process it. We can recite information ad nauseam, but how much do we actually know?

        Two questions you can NEVER ask!

        1. What is a billion?
        2. What is 1/2/2013?

        WHY?

        #1? AMERICANS would say 1000 million. Many others would say a million million!
        #2? AMERICANS would say 2nd of january 2013. Many others would say 1st of february 2013!

        BTW you can ALSO never ask how many grams in an ounce, how many ounces in a pound, etc....

                I used to sell an investment that was "8% compounded monthly". Which meant it was an annual rate of 8%, and the monthly portion of that 8% interest was compounded monthly. The effect was negligible, but it sure sounded good. It was also impossible to calculate.

                  I figured it out. 8% annual=8%APY. 8% annual, compounded monthly=8.299950680751% annual, approximately. With the rule of 72, that is ~8.675 v 9 years to double your money. OBVIOUSLY daily compounding would even get you MORE. On $1,000,000 principle, that is an extra ~$2999.51 more each year! So it all adds up.

                    It's possible you are being too kind, Steve. Companies that want you to borrow from them tend to stress the APR; those that want you to invest with them tend to promote their APY. (See APR and APY: Why Your Bank Hopes You Can't Tell The Difference.)

                    What Claude was selling more likely had an APY of 8%. To get the APR, you just take the twelfth root of 1.08, i.e., 7.72%. Still a significant difference, but to the investment firm's favor.

                    Speaking of which, I'm toying with the idea of investing with Prosper, who are offering as much as 9% to 11% APY at the high end. Does anyone here have any thoughts on them?

                      I did the math on which mobile phone plan was the cheapest!

                      It took about 4 months, and drove me a bit nuts!

                      When you sift through all the gobbly-gook math, all plans are basically the same, but as this thread has said, most wouldn't bother!

      My mother was a bookkeeper for a bank and when computers were nothing more then keypunch machines I would help updating interest on peoples accounts.
      So when I read that question my first thought was "how is the interest accrued?"

        Yes, as long as we're talking about imaginary banks they might as well use one that pays monthly ... and it should have free popcorn.

          GOOD POINT! Many such values ARE compounded daily!

          BTW How many days in a year? Many financial formulas say 360! How many days in a month? Many financial formulas say 30!

            You are correct, sir. Every bank I've worked for has used 30 and 360 for calculation purposes.
