What to bring to the exams:
 Student ID ("One" Card).

Calculators or formula sheets are not permitted. (You will have no need
for the
typical functions of a calculator during exams, as all the computations
will be
simple enough that you can do them in your head. On the other hand, an
extremely sophisticated calculator could give some students an unfair
advantage.)

NOTE 3: The
Course Description: Systems of linear equations. Vectors in nspace, vector equations of lines and planes. Matrix algebra, inverses and invertibility. Introduction to linear transformations. Subspaces of nspace. Determinants. Introduction to eigenvalues and eigenvectors. The dot product and orthogonality. Applications. Math 125 is an enriched version of MATH 120. It covers the same basic topics as MATH 120, but in greater depth and additional applications. MATH 125 is recommended for students who plan to take further courses in algebra. Math 120 cannot be taken for credit if credit has already been obtained in MATH 102, 125 or 127.
