Problem is that those cartridge nozzles that deposit tiny droplets of ink precisely when and where you want them are pretty close to magic.

They’re about as easy to manufacture as microchips, and they’re also the one part of the inkjet printer that you absolutely need to be on point if you want it to print right.

I’m surprised we don’t have open source laser printers though, that’s still hard but should be doable, if you can source the material for the rollers and figure out the led strip that charges it?

Math notation is just terrible in general because a lot of it is shorthand made up by someone who likes single-letter variables. A symbol you can’t type, something above, something below.

A for loop is clear and descriptive.
Or if you’re feeling fancy, you could go functional with reduce(add, range(0, 5), 0).
