Topic: MathHow can I pour 4 gallons of water into a 5 gallon jug (there are no markings in the jug and I have an unlimited supply of water)? Please help me explain this step by step.

Fill the 5 gallons jug and then pour the 5 gallons of water into a four gallons jug. The 4 gallons left are thrown.
Pour 1 gallon from the 5 gallons jug into the 4 gallons jug. You need 3 gallons more to fill the 4 gallons jug.
Fill again the 5 gallons jug and pour 3 gallons to complete the 4 gallons jug.
There are left 2 gallons of water.
