Well, then you're gonna love electrical engineering: Adding a 10 Ohm resistor in parallel to another 10 Ohm resistor gives you a total resistance of 5 Ohm. Which is why you don't write 10 Ohm + 10 Ohm in this case, but 10 Ohm || 10 Ohm = 5 Ohm.
This would solve your problem as well – just overload a different operator: 500 millimorts || 500 millimorts = 750 millimorts.

- keeganpoppen 6y agolol i don't know why this is being downvoted it just plainly wasn't a good example to use... there are two ways to combine resistors and they just arbitrarily took the one that doesn't add linearly, while the other one... does. and if you asked me (ie a layman) to "add two resistors together", i sure as hell wouldn't wire them in parallel lol.
- adwn 6y ago> [...] it just plainly wasn't a good example to use... there are two ways to combine resistors and they just arbitrarily took the one that doesn't add linearly [...] Nothing arbitrary about it. But if you don't like putting resistors in parallel, go ahead and put them in a series, and then compute the electrical conductance of the pair: 10 S "+" 10 S = 5 S ("S" is Siemens) > and if you asked me (ie a layman) to "add two resistors together", i sure as hell wouldn't wire them in parallel lol Maybe that's the reason why people don't ask you to fix their wiring or to design their schematics for them? Parallel impedances are just as ubiquitous and important as serial ones.
