Students in Mr. Jackson’s class are simplifying an expression written on the board:
$${{-12p-5n+8n+20p}}$$
Amal simplified the expression to be $${8p+3n}$$, and Andre simplified the expression to be $${-32p-13n}$$.
Mr. Jackson saw a few different answers around the classroom, so he gave the students a hint on the board, writing:
$${{-12p-5n+8n+20p}}$$
$${-12p+20p-5n+8n}$$
$${(-12+20)p+(-5+8)n}$$
