May 8, 2015 – Quiz Time Clear everything off of your desk except pencils, erasers, a ruler, and a non-graphing calculator. If you appear to be talking, looking at anyone else’s quiz, allowing another student to look at your quiz, or using any unauthorized aide, you will receive a zero. 30 minute time limit (except for students with an IEP or 504)

Basic Matrix Operations – Addition, Subtraction, and Scalar Multiplication Section H.07 Advanced Integrated Math I

Matrices A rectangular (two-dimensional) array of numbers/variables/expressions is called a matrix. An array is an ordered arrangement. The plural of matrix is matrices. A matrix is like a table without the lines or labels.

Matrix Addition and Subtraction Only matrices of the same size can be added or subtracted. Add/subtract the corresponding entries.

Warm-Up: May 11, 2015

Scalar Multiplication Scalar multiplication is when a matrix is multiplied by a constant. The constant is a scalar. Multiply every element of the matrix by the scalar.
