An addition
In \( \mathbb{R} \) we define the sum of two sets \(A, B \) as follows:
$$A+B = \{ a+b , \; \; a \in A, \;\; b \in B \} $$
Find the sum of \( [a, b] + [c, d] \).
$$A+B = \{ a+b , \; \; a \in A, \;\; b \in B \} $$
Find the sum of \( [a, b] + [c, d] \).
Imagination is much more important than knowledge.
