Expand or collapse the matrix to the correct size and enter the correct values for each matrix element.

Questions with a matrix require you to provide an answer in matrix or vector format.

Note If the
matrix is expandable, you determine the number of boxes, rows, and columns for the correct
answer. The default number of answer boxes shown is not necessarily the number of the answer
boxes for the correct answer. You can modify the number of answer boxes by clicking the:

- right arrow to increase the number of columns
- left arrow to decrease the number of columns
- down arrow to increase the number of rows
- up arrow to decrease the number of rows
