In math class


When you look at me
Rational numbers get irrational
The real, imaginary
And the complexes are perplexed.
When you look at me
The triangle goes still
The square circle
And the square is reversed.
When you look at me
Sets are without elements
The subsets, larger than the sets
And the emptiness disappears.
When you look at me
Multiples get prime
The cousins ​​brothers
And all the numbers are divisible.
When you look at me
The deltas are negative
The rootless equations
And the functions are without domain.
When you look at me
Derivatives run out of bounds
The graphics without inflection
And the tangents don't even touch each other.
When you look at me
Polyhedra are faceless
The concave turns convex
And Euler's theorem is nonsense.
When you look at me
The system is impossible
The matrix, round
And the determinant nullifies itself.
When you look at me
The signal is muted
The class without teacher
And the student slaps his finger on my shoulder:
- Master, class is over.
