## Importance of Rank and Nullity

Matrix rank and nullity play pivotal roles in understanding the properties and behavior of linear transformations. Each concept contributes uniquely to the mathematical narrative:

**Rank (Rank(A)):**Represents the maximum number of linearly independent rows or columns in a matrix. It provides insights into the matrix’s dimensionality and its ability to map vectors to a lower-dimensional space.**Nullity (Nullity(A)):**Reflects the dimension of the null space, indicating the number of free variables in a homogeneous system of linear equations. Nullity complements rank, shedding light on the dimension of the solution space.

Together, rank and nullity form a fundamental relationship expressed by the Rank-Nullity Theorem: `Rank(A) + Nullity(A) = Total Number of Columns (n)`
