Create large, square brackets using Word’s Shapes feature.

Matrices are used in math, physics and computer science to represent an arrangement of numbers, equations or symbols. Often, matrices need to be manipulated, added, subtracted, multiplied or analyzed in some way. Because a matrix is simply a table of numbers, it is usually straightforward to enter numbers without resorting to special math software. However, you need to add large brackets on either side of your matrix to complete it.


Step 1

Click the "Insert" tab on the ribbon, then click "Shapes" and select the left bracket from the "Basic Shapes" section to display a symbol that looks like a black cross.
