# [racket] What is the equivalent of ToExpression in Mathematica?

I am looking for something similar to
ToExpression<http://reference.wolfram.com/mathematica/ref/ToExpression.html>
that
is available in Mathematica. I just want to convert a string to an
expression, and evaluate the expression. As a first pass, my strings will
include only numbers and arithmetic operators, and not even parentheses.
If I need to write it, please point me in the direction of the appropriate
pre-defined modules/definitions which I should use.
Thanks,
% ashok
