# Enter The Matrix

**Computer Science**Level 4

Find the number of *simple arithmetic operations* one would need to perform to calculate the determinant of a general \(10\times 10\) numerical matrix by the method of Cofactor or Laplace expansion along a particular row/column.

**Details and Assumptions:**

A

*simple arithmetic operation*is one of Addition, Subtraction, Multiplication, Division.As a few explicit examples, we need to perform \(0\) operations to calculate determinant of a \(1\times 1\) matrix, \(3\) operations for a \(2\times 2\) matrix, and \(14\) operations for a \(3\times 3\) matrix.
