U=1,2,3,4,5,6,7
You asked:
Given the below definition for a set:
\[\begin{align*}& U &=& \left\{1, 2, 3, 4, 5, 6, 7\right\}\end{align*}\]Evaluate the set by simplifying it and computing its cardinality.
MathBot Answer:
The set is already an enumeration of its elements: \[\begin{align*} &\{1,2,3,4,5,6,7\}\end{align*}\]
The cardinality of the expression is $7$.
