write an m-file using while loop which calculates the sum of elements within the following vector x=[5 2 -9 10 -1 9 -1] until a number greater than 8 is met? please help i have tried and i am confused on how to do this.

general outline would be x=[5 2 -9 10 -1 9 -1]; while currentsum<=8 currentsum = %what you want to sum up. end

Why isn't three divided by two 1.5?

because it's rounding due to your setting x and y as integers and not double or single precision.
