Your age plus your birth year add up to 2017!
Ya got me! Didn't think the Facebook post thru.
I shoulda known better. Half the quizz and puzzle stuff on there only has an advertising purpose.I'm not on FB, but someone with a November or December birthday should mention it not working today..

Had to go to store for wife,and got to laughing at my self stupidity. Take ANY birth year and add your age and you come up with present year.
And I was in the top 94% in math!
Yeah- learned that one in high school- math teacher was a wizard and whenever a student couldn't get a trig problem he just went to a giant slide rule hung above the chalkboard and worked the problem solutions while explaining each step. Still, with all my learning, I pulled this one while working at Walmart. A customer called about the price of a rifle and after I told him retail he wanted to know price with tax. I told him I couldn't use the register without a sale, hoping to avoid having to figure the tax then add it to the retail- I was busy! The young high school student working with me said "Wait". The tax rate here was 8 1/4¢ . He got on the calculator and multiplied the retail X 1.0825 and handed me the price!Like any number ending in 5 multiplied times itself (squared).
Solution can be had by using the value of number preceding the numeral 5 and multiplying it by one number value greater than itself, then put the number 25 on as suffix to the product of the two numbers.
For example 25x25 can be solved by taking the number 2 X (2+1) 3= 6
Take the 6 put the number 25 with to come up with 625.
Will work for all, but if decimals are involved just place them appropriately with your finished number.

Well, of course not. The years previous and up to 2017. The joke was that your birth year added to your age would give you the present year. One of those "Duh" moments.Only once in 1000 years? my birthday in 2018, my age and my birth year will NEVER add up to 2017, no matter how long I live, be it 10 years, or 10,000 years.
Sounds like a case for Srinivasa Ramanujan to solve.
There is a famous anecdote about Ramanujan, a famous Indian mathematician, that even a non-mathematician can appreciate.
In 1917 Ramanujan was hospitalised in London. He was said to have tuberculosis but it is more likely this was to cover a failed suicide attempt.
His friend and also a mathematician, Hardy, took a cab to visit him. Not being good at small talk all Hardy could think to say was that the number of his cab, 1,729, was uninteresting.
Ramanujan immediately replied that quite to the contrary it was the smallest number expressible as a sum of two cubes in two distinct ways:
1,729 = 12^3 + 1^3 = 10^3 + 9^3
This is now known as Ramanujan’s taxi-cab number.
(note: "^" means raised to the power of).
Well, of course not. The years previous and up to 2017. The joke was that your birth year added to your age would give you the present year. One of those "Duh" moments.
But it doesn't for me - my birthday hasn't occurred yet. Mine still only adds up to 2016
What if you were born on Dec 31st? Then it's only true one day a year.
