An example how the while loop works

If we have to do 1+2+3+4+...+10

```s=0;
k=0;
while  k<10
k=k+1;
s=s+k
end
```

For homework questions it is recommended to show, what you have tried already. Then the forum can help to solve a specific problem.

Note that Gauss has found a formula to solve the addition in several seconds without a computer. You can re-order the terms of his formula to solve your problem also.
