I had a dream where I learnt how to make a calculator from a scrap of wood and a Windows program. You too can follow these simple steps to make your own calculator from scratch.
It can either be raw wood from a tree, or a piece of scrap wood, for example, skirting board, shelving etc.
The calculator didn’t actually work after all that – I mean, it worked, but it didn’t get any sums right. But hey. I made it myself.
