Step-by-Step Solution

1.For a 2×2 matrix: det(A) = a₁₁×a₂₂ - a₁₂×a₂₁
2.det(A) = 4×3 - 3×6
3.det(A) = 12 - 18 = -6

Example Calculations

2×2 Determinant

Matrix A:

[4 3]
[6 3]

det(A) = 4×3 - 3×6 = -6

Matrix Addition

A + B (element-wise):

[1+4 2+3] = [5 5]
[3+6 4+3] = [9 7]

Understanding Matrix Operations

What is a Matrix?

A matrix is a rectangular array of numbers arranged in rows and columns. Matrices are fundamental in linear algebra and have applications in computer graphics, engineering, economics, and data science.

Common Operations

  • Determinant: Scalar value indicating invertibility
  • Transpose: Flip matrix across main diagonal
  • Inverse: Matrix that undoes original transformation
  • Trace: Sum of diagonal elements

Matrix Arithmetic

Addition/Subtraction:

C[i,j] = A[i,j] ± B[i,j]

Multiplication:

C[i,j] = Σ(A[i,k] × B[k,j])

Determinant (2×2):

det(A) = a₁₁×a₂₂ - a₁₂×a₂₁

Note: Matrix multiplication is not commutative (A×B ≠ B×A), but addition and subtraction are commutative.
