CHAPTER 2 — Column and Row Matrix Addition

Here are some of the terms we have been using:

• point — a geometric object; a location in 3D (or 2D) space.
• vector — a geometric object that has properties of direction and length, but not location.
• column matrix — an ordered list of numbers arranged into a column.
• row matrix — an ordered list of numbers arranged into a row.
• element — one of the numbers that makes up a column or row matrix.
• dimension — the number of elements in a column or row matrix.
• displacement — the difference between two locations, expressed as a vector.

This chapter discusses addition and subtraction of column and row matrices.
