How do you use the distributive property to simplify 3(n+1)?

$3 \left(n + 1\right) = \textcolor{red}{3 n + 3}$

Explanation:

The distributive property tells us that (in general)
$\textcolor{w h i t e}{\text{XXX}} a \left(b + c\right) = a b + a c$

$\textcolor{red}{3} \left(n + 1\right) \implies \left(\textcolor{red}{3} \cdot n\right) + \left(\textcolor{red}{3} \cdot 1\right) \implies 3 n + 3$
