What to Focus On

  • A matrix is a rectangular arrangement of numbers.
  • It is denoted by a capital letter.
  • Elements are arranged in rows and columns.

  • Order = number of rows × number of columns.
  • An $ m \times n $ matrix has $ m $ rows and $ n $ columns.
  • Total elements = $ m \times n $.

  • Row matrix: 1 row, any columns.
  • Column matrix: 1 column, any rows.
  • Square matrix: rows = columns.

Common Mistakes to Avoid

Matrix multiplication is commutative, so AB = BA always.

You can add or multiply any two matrices as long as they look similar.

A zero matrix means the matrix has no elements.
