The notation just means
(f/g)(-4) = f(-4) / g(-4)
If f(x) = x² + 2 and g(x) = 1 - 3x, then
f(-4) = (-4)² + 2 = 16 + 2 = 18
g(-4) = 1 - 3 (-4) = 1 + 12 = 13
and so
(f/g)(-4) = 18/13
This is an example of division. 252/6=42. So 42 toys will go into each pinata.
So close! But instead of adding the multiplication sign after the number you need to add them before. Good job though! :)
