Question 4 If 47 – 56 + 14 – 8 + 2 – 8 + 5 = – 4, then find the value of – 47 + 56 – 14 + 8 – 2 + 8 – 5 without calculating the full expression.Notice that Every single number in the second list has the opposite sign of the first list. 47 became –47 –56 became +56, and so on. If you flip the sign of every number in a sum, the final answer also flips its sign. Since the first answer was -4, the new answer is 4.
