It is very simple and easy mate you can understand this with just one click, now here I am trying my best to understand you in very easy Words and short as as possible. Supply and demand are the two elements that occur in every market. They work on a very simple rule i.e. when one increases the other decreases and when one decreases the other increases.

Let us understand this in the trading world. In trading supply is the amount of tokens cryptocurrency or commodities which are present for purchase. When the supply is high it makes the price down because there is more seller who want to sell.

The same is the demand, the assets that the crowd desires or willingness to buy at a specific price. When the demand is high the price increases because of the larger buyers present in the market.

This is the simple explanation of it, hope you and those who did not understand demand and supply take benefits from this.
