How do I complete the Red Leaf High math quiz room?

To add to this, has anyone had a question that was not in a W + X * Y + Z format? I've had the same format every single time (20+) so it might just be easier to tell people X * Y + W + Z.

Idk, teach a man to fish? I think its better for everyone if they just learned a tiny bit more about math for their own sake.
