Answer:
result = 0 + 2 - 4
Step-by-step explanation:
The leftmost arrow starts at 0 and goes 2 units in the + direction. The right arrow starts from there and goes 4 units in the - direction.
The left arrow represents adding 2 units to 0. The right arrow represents adding -4 units to +2, or subtracting 4 units from +2. The equation could be written as ...
result = 0 +2 -4
result = 0 +2 +(-4)
__
Additional comment
There are additional ways to write this in consideration of the fact that +2 = -(-2). The 0 doesn't need to be part of the equation. It is put here to indicate the fact that we start from 0. Without it, the "starting from 0" is implied.
