**Equal** of Matrices

Two matrices are equal if and only if these matrices have the same dimensions and equal corresponding elements.

#### Which matrices below are equal?

All three matrices have the same dimensions

- 3 × 3 (3 rows and 3 columns)

All corresponding entries or elements are the same in matrix 1 and matrix 3.

- The middle most entry of matrix #2 is not the same as the corresponding entry in the other matrices. Therefore, matrix #2 does **not equal** either of the other ones.
