_V_a_l_u_e:

     These binary operators perform arithmetic on vector
     objects.  They return numeric vectors containing the
     result of the element by element operations.  The ele-
     ments of shorter vectors are recycled as necessary.
     The operators are `+' for addition, `-' for subtraction
     `*' for multiplication, `/' for division and `^' for
     exponentiation.  `%%' indicates `x mod y' and `%/%'
     indicates integer division.

     Objects such as arrays or time-series can be operated
     on this way provided they are conformable.

_S_e_e _A_l_s_o:

     `Math' for miscellaneous and `Special' for special
     mathematical functions.

     x <- -1:12
     x + 1
     2 * x + 3
     x %% 2
     x %/% 5
