62
6
I love math. But I can't find a single calculator that can multiply correctly. They seem to get everything right except 6*9 (It's the question to life, the universe, and everything! How could they get that wrong?!). So I want you all to write a function for me that can multiply 2 numbers correctly (and 6*9 equals 42 instead of 54. 9*6 equals 54 still).
Oh, and I'm going to have to build the source in Minecraft so... fewest bytes win!
Recap
- Take 2 numbers as input (type doesn't matter, but only 2 items will be passed, and order must be consistent. So streams, and arrays are ok as long as they preserve the order they where passed in. I.e., a map won't work because it doesn't preserve the order)
- Output multiple of both numbers except if they are 6 and 9, then output 42 (order matters!)
- PS. I never was really good with counting, so I think only integers from 0 to 99 are real numbers (type used doesn't matter)
- Fewest bytes per language wins!

May the input be a list of numbers? – Jonathan Allan – 2017-06-02T22:14:41.553
@MartinEnder Added rules to address that – Tezra – 2017-06-03T04:09:25.240
1@JonathanAllan Yes, added rules for that. – Tezra – 2017-06-03T04:09:49.563
74Coincidentally the question id has
42
twice in it. – Erik the Outgolfer – 2017-06-03T06:00:18.5502if only integers up to 99 are real numbers, then e.g. 9 * 11 is a valid prompt but 10 * 10 is not, right? – Please stop being evil – 2017-06-03T08:23:34.537
@thedarkwanderer. 0 to 99 is the valid input, 0 to 9999 is the valid output – Tezra – 2017-06-03T13:45:16.377
14@EriktheOutgolfer …and the 12 stands for what to subtract if input is 6 and 9. – Adám – 2017-06-03T23:43:26.960
1@Adám Just the absolutely perfect question id for this question. – Erik the Outgolfer – 2017-06-04T07:16:01.110
11@EriktheOutgolfer Even if you read the ID backwards. – T. Sar – 2017-06-05T12:57:47.867
142 is 54 in base 13. Note that 6 and 9 are valid in base 13 One answer has that, surprised not more – Michael Durrant – 2017-06-05T13:24:33.813
When I saw the title, I expected it to be about finding bases where the equation is true but it turns out that already exists.
