What do the answers of the following: - 3 + 4 - 5 - 5 + 4 + - 3 - 3 + - 5 + 4 4 + - 3 + - 5 Is this true for any three integers?

Given, - 3 + 4 - 5 - 5 + 4 + - 3 - 3 + - 5 + 4 4 + - 3 + - 5 To find the value of - 3 + 4 + - 5 , First we add - 3 and 4 , then add - 5 to the answer. So, - 3 + 4 + - 5 = - 3 + 4 + - 5 = 1 + - 5 = - 4 Similarly, - 5 + 4 + - 3 = - 5 + 4 + - 3 = - 1 + - 3 = - 4 - 3 + - 5 + 4 = - 3 + - 5 + 4 = - 8 + 4 = - 4 4 + - 3 + - 5 = 4 + - 3 + - 5 = 1 + - 5 = - 4 Thus, the answer is - 4 for all the four operations. According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped. Hence, it is true for any three integers.
