Q1
Estimate and then compute exactly to check reasonableness: A water tank is $-1.8$ liters (it needs $1.8$ L to be full). First, $3\tfrac{1}{2}$ liters are added. Then $0.6$ liter leaks out. Finally, $\tfrac{1}{4}$ of the current amount of water is drained for cleaning. What is the final amount of water in the tank (in liters)?
