Zero is neither positive nor negative.
Step 1: Positive numbers are greater than zero.
( ext{Positive} Rightarrow x > 0 )
Step 2: Negative numbers are less than zero.
( ext{Negative} Rightarrow x < 0 )
Step 3: Check zero.
( 0 ot> 0 )
( 0 ot< 0 )
Step 4: On the number line, positives are to the right of (0), negatives to the left. Zero is at the center, not on either side.
Step 5: Zero has no sign. Writing a minus does not change it.
( -0 = 0 )
Conclusion: Zero is neither positive nor negative.
