For Loops for Summation Problems

I need to create a 'for' loop for the following summation:

x1 = 80000 - sum(0.1) from k=1 to k=800000. The point is to show that while this should equal zero, MatLab will add up all the minor errors until it creates one large one.

I have tried reading through the posts on here and watching videos, but I cannot figure out how to enter this into MatLab without getting an error or an infinite loop. I am very new to MatLab, so any help would be appreciated.

Thank you!

In this statement the value of x is not change

x1=80000-sum(0.1)

Whatever the number of iterations you performed

[Stephen23]

for k = 1:800000
    x1 = 80000 - sum(0.1);
end

But nothing in your calculation depends on k, so I don't really see the point.

That is what I thought, but this is exactly how it is written in the problem. I thought it was an error, but there are four different problems like this with slightly different numbers, and none of them include a k value in the summation equation.

Well, looking at your description of the problem, I guess you could do something like this

 x1=80000;
 for k = 1:800000
     x1 = x1 - sum(0.1);
 end

x1 =

    -1.687279162776445e-07

so the answer is not zero, lesson learned.
