find the sum of the digits of the numbers between 10 and 19 inclusively.
The sum is given by:
[19 + 10] * 5 = 29 * 5 = 145
Why don't you just add them up on a calculator? Too much work? At any rate the total should be=145
Unless you wanted the sum of individual digits such as10=1 and 11=2.......etc.in which case the answer would be=55. Make sure what they want.
