You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you the answer but how can you be sure that I did not make a mistake? Or that I am not messing about?
The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.
The total sum is 110
(-15) + 23 = 8
-7
The sum of -15 and -35 is -50.
