The Crabby Apple restaurant lost $2000 in the month of January. If their net worth at the end of the month is -$200, explain how you would show a child how to find their net worth at the beginning of the month.
if they lost 2000 from their starting value, you need to gain that much to get back to where they started:
-200 + 2000 = 1800
use the number line to show how losing money means going to the left, and gaining it moves to the right.
