The sum of the first eleven positive odd integers is 121.
Yes, all whole numbers, negative and positive are integers.
They are positive integers, evenly divisible only by themselves and one.
1,2,3,4,5,6,7,8,9,10 and 11 Integers are the whole numbers such as one, two, thirteen, a million, etc. I listed the ones which are positive - grater than zero - and smaller than or equal to eleven
7 and -4
The formula for the first n positive numbers is n x (n+1)/2, so for n=11 the sum is 11 x 12 /2 = 66
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
positive 5 minus positive 11 = negative 6
Negative eleven plus twenty is positive 9.
