Michelle’s wardrobe is made up of 2 pairs of pants (black and gray), 3 shirts (pink, blue and flowered), and 2 sweaters (white and green). How many different outfits does she have?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
