In the month of May, mathematician Maria Gaerana was born in Italy. Maria was a gifted child who spoke more than a dozen languages by age nine. Her love however was mathematics, and even in a time when women were not educated, she became famous for her published books on mathematics. Solve the following to find out what year she was born.
The two digit number formed by my tens and units is one greater than the two digit number formed by my thousands and hundreds digits; their sum is 35.
What year am I? __ __ __ __

Hint
You don't have to find the remainder.Answer
To find the digits you have to first divide then subtract.1) 35/2 = 17
2) 35-17 =18
Therefore, the year is 1718.

Took me a minute but got it! Good one
it's suppose to take everyone a while.
Why couldn't it be like 1619 or 1520?
It couldn't be 1619 because the numbers in the ten's place and one's place had to be 1 greater than that in the thousand's and hundred's place.
Good one. Simple matter of guess and check. However it was interesting

no guessing required. If the two two-digit numbers added together equal 35, and one number is only 1 greater than the other, then you can subtract that 1 from the 35 = 34 = 2x the smaller number.
very good and simple.
I'm afraid Maria would be ashamed to have such a weak math problem associated with her name. I'd call it a teaser, but it just isn't.
