Integration is an important concept in mathematics which, together with differentiation, forms one of the main operations in calculus.

Large Integration is the process of integration with long equations. That is to say equations with over 100 terms.

Very Large Scale Integration is a term that can be used when the number of terms to be integrated is even greater.

Very Large Scale Integration is normally carried out by computer. It is not recommended to be undertaken lightly by a human as it can cause mind boggling. The sheer number of algorithms and data structures that need to be assimilated means this sort of architecture is often very specialised.

Intergration is often considered a harder technology than differention. Integration is sometimes introduced as the reverse of differentiation. If we have a table of derivatives, we can read it backwards as a table of anti-derivatives.
