A Long time ago,there was a place called West Africa. That's where these people called Wangarans, who liked to trade gold for salt, and the Taghaza people who want to trade salt for other necessities. There was also these tax collectors who told you where to go to get to the Wangarans.
I would like to go get some gold with the Wangarans today,so I can use that gold for many other great things.
So off he went to go to the Taghaza for the salt to trade with the Taghzans.
Can I have some salt? I'll give you food and water or 2 pounds of salt.
They trade salt for food and water. But after he had traded with the Taghazans he went of to Ghana.
May I pass? I need to get to the Wangarans!
Yes,but first you HAVE to pay tax,and thats 1 gold nugget.
