MathObjects reduces mathematical expressions according to a set of reduction rules. These control which expressions are reduced. Reductions can be turned off in two ways:
For all subsequent reduce
operations in the problem:
Context()>reduction>set('x/1'=>0);
For a single reduction:
$f>reduce('x/1'=>0);
