Linear Algebra

2. (a matrix with the same number of rows and columns)
4. (a concept that describes something greater than a natural number)
9. (different terms and expressions with a similar value are considered equal in mathematical form)
12. (procedure, a description of a set of steps that can be used to solve a mathematical computation)
13. (On a two-dimensional graph, it is the intersection of the X-axis and the Y-axis, sometimes written as the letter O)
14. (Arectangular array of numbers, characters, or expressions arranged in rows and column)
15. (The term that refers to the stair-step pattern formed by the nonzero elements of the matrix)

1. (the set of all n-dimensional column vectors x such that Ax = 0.)
3. (a point at or near the middle of, or equidistant from, both ends, as of a line:)
5. (If a matrix is in row-echelon form, then the first nonzero entry of each row is called a)
6. line (is the union of infinite points joining on either side of a point.)
7. system (a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points)
8. (the property of an object to be able to be divided into two identical mirror halves)
10. (the region of the Cartesian plane formed when the x-axis and y-axis intersect)
11. (the difference between a true value and an estimate, or approximation, of that value)
