noob needs help with math how to avg the price you paid?

So I made a couple of buys at different prices and I want to figure out the average price I paid and the total coins I have. But its been so long since college I cant remember how to do the math. This way I can find my break even price. Thats all that matters is the avg of what all my trades were vs the price I paid correct, the individual trades dont matter? To think I once memorized an entire series 7 book when I was a kid, old age forgets) Heres the info I tried to get a nice neat .jpg but I dont think you can attach files to this site.
