Hereโs another small item I lifted from Facebook.....

Add your age to the year you were born. NO MATTER WHO YOU ARE, THE SUM IS 2020?

Is this true? I did the exercise. I was born in 1950, and I turn 70 in November ๐ฒ

Truth is stranger than fiction. Maybe Mel/Compiler or one of our other math teachers can explain it.

Um, the difference between the current year and your birth year is how we calculate/define your age. So, to check your subtraction, add your age to your birth year and you should get the current year. QED ๐

LOL. The magic of 37:

37x 3= 111

37x 6= 222

37x 9= 333

37x 12=444

etc.

It will be the same answer in 2020 and next year too!

37x 3= 111

Born 1960. 60 years of age. Comes out to 2020.

I'm not going to think about it too hard. Lupron brain.

2+2=4. This year and next year. And every year after.

I bet bucks that next year when you add your age and birth year it will equal 2021. Last year I added my age and birth year and it equaled 2019. Who knew?

Must be the new math...

Prato - It sounds like you are 69 currently which would make the year 2019 by the simple definition you provided in the initial post.

Seems that oneโs birthdate might be important unless I missed something.

You need to use your age on your birthday in any given year for it to work out. Iโll be 70 in November

Posted 10/11/2020 6:36 PM (GMT -6)

Here's another birthday-age math puzzle

Enter the number of days per week that you exercise (more than one)

Multiply the number selected in #1 by 2

Add 5

Multiply by 50

If you have already had your birthday this year, add 1770. If you have not had your birthday yet this year, add 1769

Subtract the four digit year of your birth

You should end up with a 3-digit number

The 1st number represents the number of days you exercise per week and the next two

numbers are your age !

Well, 37X6 = (37X3) X2, so double the previous answer, hence 222.

37X9= (37X3) X3, so triple the first answer, hence 333.

Ken, back to your original statement which is actually not correct. As you stated, you are currently 69 and born in 1950. That sum today and for most of the year is 2019, not 2020.

So the statement is only correct for people who have already had their birthday. If one is born on January 1, the statement is true for 365 days. For the person born on December 31 it is true for only one day.

Remember, Abe Lincoln cautioned that not everything on the internet can be believed. I saw that on Facebook.

Another fun number is 9. When you multiply it by another number, the sum of the digits in the answer equal 9.

9x2=18. 1+8=9

7x9=63. 6+3=9

9x12=108. 1+0+8=9

9x27=243. 2+4+3=9

There are exceptions when the answer starts having 3 or more digits, such as, 9x32=288. 2+8+8=18. But then 1+8=9. Another is 9x87=783. 7+8+3=18 and 1+8=9.

Have fun.

The sum of odd number numbers is always even. The sum of even numbers is always even. I've always thought that was odd. ๐

JNF - That is how multiplication by 9 was taught to me as a check in school. Of course, 10's were easy and 11 had the progression of 11, 22, 33, 44, 55, 66, 77, 88, 99 so easy to remember that rule. The real world taught me 12's since feet and inches were/are common and the portable calculator was invented later.

What I find interesting or concerning is my boys and most younger people can not do any math in their head whereas my 93 year old father is and always has been a mental math wizard. A pencil and paper makes him extremely dangerous.

My great grandfather was a math professor at University of Washington so there must be a math gene floating around somewhere that some of us have and others don't.

It is true if you use your age on your birthday of that year. So using 70, for example, which i turn 70 in 2020, it works.

As it should, simple math

Mattam, 81GyGuy, with your most recent posts, this thread is definitely heading towards the nothing thread. We may have to request from Admin that we have a subforum titled NOthing. Nothing, can be a disease after all, if looked at in the right perspective

Posted 10/12/2020 10:38 AM (GMT -6)

By the way, this thread started on 10/10/2020. 8 years ago yesterday was 10/11/12. More magic. Hope I keep you laughing Mel.

Another way to say it is: if a number is divisible by 9, the sum of the digits is a multiple of 9. This is important in poker tourneys. Tables consist of 9 players. If you are ITM (In The Money) of a MTT (Multi Table tourney) then often the award increases every time a table goes out. So, say we have 174 players. Then when we get to 171 (digits add up to 9) the $$$ increases. So I play conservative until 3 players go out.
