%description
When using the R package 'exams' to write mathematics questions in
'Sweave' files, the output of a lot of R functions need to be adjusted for
display in mathematical formulas. Specifically, the functions were
accumulated when writing questions for the topics of the mathematics
courses College Algebra, Precalculus, Calculus, Differential Equations,
Introduction to Probability, and Linear Algebra.  The output of the
developed functions can be used in 'Sweave' files.
