Interesting. The other reply to this, along with its subthread, assumes that "calculating" means "calculated using a digital computer".

Does anyone know what I do in my head when I calculate 4 + 4 is 8? Does anyone know what they do in their own head to calculate 4 + 4? Is that process the same as 2 + 2? as 38 + 153?

Few people know what happens in a computer to calculate the same. And that it is potentially very different depending on what the instructions are used to do it. :D
