I am honestly so lost with this question, because 1) the wording is awful and 2) I just don't get while loops. The full question is "Let Sn be the sum of integers that are between 1 and n and are dividable by 11. Write a script program that inputs a large positive integer M, computes the smallest integer n∗such that Sn∗> M, then displays n∗and Sn∗." I have this so far.

%Small integer

M=input('Enter number M:');

n=1;

rem(n,11)=0;

while Sn<=M

if rem(n,11)==0

end

n=n+1;

Sn=n;

end

Sns=Sn;

ns=n;

fprintf('ns=%f\n', ns)

fprintf('Sns=%f\n', Sns)

I just don't know what else to put

You have done quite well despite your limited understanding of the question. Your code requires only a few modifications -

%M=input('Enter number M:');
%random large positive integer
M=123456;
%initiating the sum as 0
Sn=0;
n=1;
while Sn<=M
    if rem(n,11)==0
        Sn=Sn+n;
    end
    n=n+1;
end
fprintf('n=%d\n', n)
n=1651
fprintf('Sn=%d\n', Sn)
Sn=124575
