The brain does not perform "calculations" in the same way a digital computer does which actually doesn't calculate anything either. Calculating is an act of intention. Computers do not have intention. Rather using a fixed and stored instruction set humans can use the combinatorial networks of computer microcode to generate a certain deterministic result. The flow is one path. Human intention->software->combinatorial machinery->result. One input one output. In contrast the brain takes multiple inputs and transforms them into controlled action in the real world in the service of goals. This action manifests as multiple complex outputs. The single neuron is a complicated analog computer. The brain is a functional network of 100 billion neurons or whatever the number is.
