**2.3 Modeling Real World Data with Matrices**

2
**Matrix – a rectangular array or terms called elements.**

Elements are arranged in rows and columns and enclosed by brackets. A matrix with m rows and n columns is an m x n matrix. The dimensions of the matrix and m and n. Named using a capital letter.

3
Two matrices are equal if and only if they have the same dimensions and are identical, element by element. Ex 2

4
**Addition – can add if same size**

Ex 3

5
**Additive Identity – for every matrix A, another matrix can be found so that their sum is A.**

6
Ex 4 Fins S – T.

7
**Scalar multiplication – multiply each element of the matrix by the scalar.**

Ex 5Find 4A if A=

8
**Matrix multiplication – the product of an m x n matrix and an n x r matrix is an m x r matrix.**

Ex 6 Find AB Find BC
