A name for two pregnancys within the same year?
I have only heard it called by the politically incorrect and derisive label of "Irish Twins". I heard this from an Italian-American from New York. I understand it to be a derogatory reference to perceived large family sizes among Irish-Americans. I believe there is long standing history of both animosity and intermarriage between Irish-Americans and Italian-Americans in the Northeast, so go figure. With any luck someone with a medical background will be able to give us the proper answer.
What is the sum of all numbers from one to one hundred?
5050
1 + 2 + 3 + . . . . + 99 + 100 = ?
Arrange the numbers to add them like this:
(1 + 100) + (2 + 99) + (3 + 98) + . . . . + (50 + 51) = ?
If you notice every pair of numbers adds up to 101. There are 50
pairs of numbers, so the answer is 50*101 = 5050.
In general to find the sum of all the numbers from 1 to N:
1 + 2 + 3 + 4 + . . . . + N = (1 + N)*(N/2)
That is "1 plus N quantity times N divided by 2."
Hope this helps.
