I am the very Model of the Modern Major General - BY GILBERT AND SULLIVAN

I am the very model of the modern major general. 

I've information vegetable animal and mineral. 

I know the king of England and I quote the fights historical

From Marathon to Waterloo in order categorical. 

I'm very well acquainted too with matters mathematical

I understand equations both the simple and quadratical. 

About binomial theorem I am teeming with a lot of news,

With many cheerful facts about the square of the hypotenuse. 

I'm very good at integral and differential calculus,

I know the scientific names of beings animalculous.

In short, in matters vegetable, animal, and mineral,

I am the very model of the modern major general. 

I liked this poem because it is unique, and it brings back memories of my childhood (I learned this poem as a child).
