  1. The Saddle Point of a Matrix The saddle point is the largest value in it’s column and the smallest in it’s row. It indicates the optimal strategy of the row player in game theory.

  2. Do you remember imaginary numbers?By definition, =iSo i2 = -1.To put i in the calculator use 2nd.Find: i4 i6

  3. Solve: x2 = -9

  4. Solve: x2 - 5 = 7

  5. A Complex number is a real number plus an imaginary numbera + biThe conjugate of a+bi is a-bi.What is the conjugate of 6+2i?What is the conjugate of 5-4i?

  6. What happens when you multiply conjugates? Example: (4+3i)(4-3i) You try: Multiply (5+2i) and it’s conjugate.

  7. Solve for B if A, B and C are matrices. AB = C B = A-1 CWrite the matrix equation, the solved equation, and then find the solution for the system. 3x + y = 9

  8. 4x-3y=-162x+5y=18

  9. Vocabulary for Matrices Dimension Order Square Address Scalar Conform Minor Determinant Adjacency Matrix
