EECS20N: Signals and Systems

Assignment and assertion

Naturals = {1,2,3, ...} and Students = {JohnDoe, JaneBrown, ...} are assignments,

4 ∈A, 11 ∉ A, and A = B are true assertions, 12 ∈ A is a false assertion.

Assignments and assertions are examples of well-formed expressions. 4 ∈ 4 is not a well-formed expression.

Note: Symbol = is overloaded since it is used for both assignment and assertion.
