matrix- a rectangular array of numbers, algebraic symbols, or mathematical functions

To determine:

• order
• position

Orders are determined by row X column

C

O

L

U

M

N

ROW $\begin{bmatrix} 9 & 8 & 6 \ 1 & 2 & 7 \ 4 & 9 & 2 \ 6 & 0 & 5 \end{bmatrix}$

Since this has 4 rows and 3 columns it is a 4X3 matrix.

Find the location:

Find a1,2

A=

The 1st # refers to the row...  the 2nd # refers to the column...

Go to the 1st row:

Number sequence: 2 3 -1 6

Go to the 2nd column:

Number sequence 3 -1 1

The row and column meet at 3.
