[Verse 1]
Started counting fingers, one by one
Natural numbers dancing in the sun
Zero, one, two, three, they march in line
But something's missing in this grand design
When I try to go backwards from three to five
The answer vanishes, won't arrive
No additive inverse can be found
In natural's realm, we're glory-bound
[Chorus]
Natural numbers have no way back home
No additive inverse, they stand alone
Three minus five equals nothing here
The problem's crystal, perfectly clear
N-set boundaries, walls so tight
Can't subtract beyond zero's sight
The gap appears when we need more
Than natural numbers can explore
[Verse 2]
Every number wants a partner true
One that adds to zero, me plus you
But naturals are stubborn, won't comply
They leave us hanging, wondering why
Seven needs negative seven's embrace
But naturals won't give it space
The equation breaks, the answer flees
We're trapped inside these boundaries
[Chorus]
Natural numbers have no way back home
No additive inverse, they stand alone
Three minus five equals nothing here
The problem's crystal, perfectly clear
N-set boundaries, walls so tight
Can't subtract beyond zero's sight
The gap appears when we need more
Than natural numbers can explore
[Bridge]
This is the crack where mathematics grows
The place where limitation shows
We need to build a bigger stage
Turn to integers' wider page
[Outro]
The problem births the solution's call
Natural numbers can't have it all
When subtraction fails to compute
We know it's time for a new pursuit
