What is the sum of integers from 1 to 10?

Answer by  Binome (1975)

An integer is a number with no decimal or fraction. So that is just another way of asking 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = ? The total is 55.

Answer by  moocow (39)

The sum of the integers from 1 to 10 is 55. The average number on the list from 1 to 10 is 5.5, and 5.5x10=55. In general, the sum of integers from 1 to X is X*(X+1)/2

if the question is the numbers BETWEEN one and ten, then it is 2+3+4+5+6+7+8+9 which equals 44. if you want to include the one and ten, then you get the 44 plus 1 plus 10 which equals 55.
