I'm watching a documentary on Blockchain and I'm trying to understand something. They said you can use your computers processing power to solve complex equations and as a reward you get a bitcoin.. Ok, but what are these complex equations that are needing to be solved and what for? What is the blockchain wanting to accomplish?

The complex equations are a security feature. The equations are unable to be worked backwards. So once that block’s equation is solved Bitcoin is rewarded to the miner who solved it. The block contains information about transactions creating a ledger that is shared with all nodes which prevents double spending.

I tried to keep my answer simple but if you’d like more information on the math behind blockchain.
