To simplify the expression $(x + 3) - (x + 2)$, follow these steps:

1. Distribute the negative sign to both terms inside the second set of parentheses: $(x + 3) - x - 2$

2. Now combine like terms: $x - x + 3 - 2$

3. The $x - x$ terms cancel each other out, leaving: $3 - 2 = 1$

Thus, the simplified expression is: $1$
