| 2026-02-15 23:02:08 +0100 | <larsivi> | ok, so slowly starting to understand this :) At least I have something that works. Thanks again! |

| 2026-02-15 22:54:59 +0100 | <larsivi> | yeah, that turns out to negate the result |

| 2026-02-15 22:54:00 +0100 | <monochrom> | If x=1/2, then 1-x = x, so (1-) looks like doing nothing. |
| 2026-02-15 22:53:11 +0100 | <larsivi> | ah, so it is the order that is wrong? |
| 2026-02-15 22:52:41 +0100 | <mauke> | that's equivalent to [(1+), (1-)] |
| 2026-02-15 22:51:53 +0100 | <larsivi> | I returned stuff like [(+1), ((-)1)] that type checked against [Int -> Int]. I was able to [op1,op2] ==> foo (op1 x) (op2 y), but the value was not changed with the subtraction unless I rewrote it to (subtract 1). |

| 2026-02-15 22:48:54 +0100 | <monochrom> | Haskell is so negative! So many ways to say subtraction. >:) |

| 2026-02-15 22:46:54 +0100 | <dcb> | I don't think you can make (-) into a section (without `flip`, or as mentioned, `subtract`) |
| 2026-02-15 22:46:50 +0100 | <int-e> | anyway, (-) 1 does *something*. |

| 2026-02-15 22:45:36 +0100 | <monochrom> | (-) 5 = \y -> (-) 5 y = \y -> 5 - y. sutract 5 = \y -> y - 5 |

| 2026-02-15 22:44:06 +0100 | <larsivi> | But it turned out that (-)1 didn't actually do anything, so had to use subtract 1 instead. Something I did wrong there? |
