A poem on positive and negative numbers

Positive & Negative

-3 -2 -1 0 +1 +2 +3

From zero's place,
On number line,
Numbers fall,
Depends on sign...
Negative left,

Positive right,

It's no doubt,
An awesome sight!
Zero- sea level,
Negative-low,
Positive- up,
That's how it goes...
A positive's good,
A negative's bad,
Both numbers, though,
Make you glad...
From zero's place,
On number line,
Numbers fall,
Depends on sign...
