You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions. I could tell you that the answer is 90 but how can you be sure that I did not make a mistake? Or that I am not messing about?
25 + 15 + 21 + 10 + 11 = 82
s = 20
10 plus 25 divided by 5 is 15
-15
The answer to this question is 60.
25 as 10+10 is 20 plus 5 is 25
25 + 15 + 21 + 10 + 11 = 82
s = 20
10+(-25)=(-15)
