Final answer:

Option A

The value of the expression 1 - 2 + 3 - 4 + 5 is 3. This was obtained by performing each operation from left to right.

Step-by-step explanation:

To solve the value of the expression 1 - 2 + 3 - 4 + 5, we follow the order of operations, which in this case, is left to right since all operations are addition and subtraction.

Starting from the left, we have 1 - 2, which equals -1. Then, we add 3 to -1, resulting in 2. Next, we subtract 4 from 2, which gives us -2. Finally, we add 5 to -2, giving us a final answer of 3.

Let's calculate step by step:

  • 1 - 2 = -1
  • -1 + 3 = 2
  • 2 - 4 = -2
  • -2 + 5 = 3

So, the result of the expression is 3, which means Option A is correct.
