- 1. The property that states that when multiplying a matrix with another matrix, the order cannot be reversed. (AB is not equal to BA).
- 3. A square matrix containing one diagonal in which all the elements are the same, and the rest of the elements are equal to zero.
- 5. Obtained by multiplying the amount of rows by the amount of columns of a matrix.
- 6. A to the power of negative 1.
- 8. A specific kind of matrix which when multiplied by another matrix (A) equals that matrix (A). It has one diagonal line of ones and the rest of the elements are zeroes.
- 10. The values for m and n in an m*n matrix. They help determine which element is being referred to in a question (example: the element at 3,5).
- 11. It can be solved by using a matrix, or a method such as substitution or graphing.
- 13. An operation used to solve for X in AX=A.
- 14. The process of flipping a certain figure (from a graph) over a line.
Down
- 2. Obtained by switching the rows and columns of a matrix.
- 4. The numbers or symbols found in a matrix.
- 7. The action of turning a figure drawn on a graph by a certain amount of degrees counterclockwise around the origin.
- 9. Used to find a matrix's inverse. If it is equal to 0, the inverse does not exist.
- 12. The vertical lines on a matrix.
- 14. The horizontal lines on a matrix.
