CAN YOU LEGALLY COLLECT THE RAIN? Rainwater collection is allowed in many states, but the rules depend on where you live, your system, and how you use the water. Colorado’s standard residential allowance is up to two rain barrels totaling 110 gallons for outdoor use on the same property. Utah allows two covered containers of up to 100 gallons each without registration; larger systems require registration and have additional limits.

This one looks simple, but it catches a lot of people if they rush. Slow down, follow the order of operations carefully, and see what you get. A lot of people will not agree on this one, which makes it even more fun. Do you work left to right? Do the parentheses change everything? That is where the debate starts.
