I want to calculate the arithmetic average of a class of 5 students for 3 different exams. I want to calculate a different average for each exam. I want to use i and j variables. exam grades will be random like 20*i. How can i do this program? Any can do this? Thank you 

I try this program but i get error

total:=0;

numb:=0;

for i from 1 to 3 do

for j from 1 to 5 do

N[i,j]:=20*i;

total:=total+N[i,j];

numb:=numb+i

end do;

end do;

evalf(total/numb);
