Answer 1

[Atsushi Ueno]

nms = [50    60   -2   -15  100];

sum(nms) % 1- find the sum of a set of five different numbers

ans = 193

sum(nms(nms < 0)) % 2- find the sum of negative numbers

ans = -17

sum(nms > 40 & nms < 90) % 3-find how many numbers are more than 40 and less than 90 

ans = 2

Answer 2

[Musaed]

%[50 60 -2 -15 100]
sum=0;
for x=1:5
    z=input('enter#')
    sum=sum+z;
end
disp('sum=')
disp(sum)
