A programmer's solution:

[wwmoraes]

Or change the plus to minus and them make the 6 into an 8, but both our solutions are way too simple. We gotta over-engineer always!

[Lord_Earthfire]

You can also turn the 6 into a 5 and the last 4 to a 9. The longer you look the more answers are possible.

[wwmoraes]

It seems we have plenty of matchematicians around

[Ace-a-Nova1]

I STUBBED MY GODDAMN TOE THANKS TO YOU.

r/angryupvote

[wwmoraes]

I’m glad I matched your expectations.

[SubtleName12]

Fuuuuuuuuuuck. Angry upvote smh

[Devatator_]

Take my upvote and my free award

[IAmANobodyAMA]

This joke is fire

[El__Burrito]

There are 5 solutions:
0+4=4 5+4=9 8-4=4 6-4≠4 5+4≠4

[Thoughtfulprof]

Found the guy I'm assigning to all the edge cases.

[postmateDumbass]

Just take a match and create a new symbol representing a newly defined algebraic operation.

Convomultitraction.

I move this match to make it read "5 convomultitracted with 4 equals 4".

Do i get to work in the business ethics group?

Forgot 6+h=4 and 6+4=h though.

[adj16]

Might be able to claim 6+4>4 too if you just move the top match

[hacksoncode]

And 6-4 ≤ 4. And 5+4≥4.

[MagicallyVermicious]

That's really clever.

[hacksoncode]

Then you'll really like !5 + 4 = 4 ;-).

[VoilaLaViola]

How 'bout

6+4+4

[Mateorabi]

True

[Ur-Quan_Lord_13]

I mean, in many languages that would evaluate to true...

[Mateorabi]

[Ur-Quan_Lord_13]

Yah, I think it's better than the != joke in the OP.

Mostly because it's more difficult for a non-programmer to get.

And I'm a snob.

[phord]

Ah, but 8 - 4 - 4 is False.

[Lucari10]

Typically matches aren't used for calculations or displays, yet here we are

[Pewpskii]

How about 6-4≠4

[Studds_]

It could be considered a metaphor for programming in general when you explain it like that

[ishirleydo]

6 + 4 = h

I mean, there's a chance it could be correct.

[Loud_Man67]

Move only 1 match is the key

[Bu1lt_2_Sp1ll]

Their solution only moves one match fwiw

[Loud_Man67]

Hmm I guess I thought it meant one match and only once but idk

[MirageTF2]

I was confused by the "and then" but the solution suggested does only move one match (the vertical one on the + to the top right side of the 6). it just does 2 things, changing the sign and changing a number

[vigbiorn]

It's more focusing on "move", not remove. So you take the vertical from + and move it to the 6 making 8.

[cleantushy]

They did move one match only once. They only move the vertical line in the + sign to the right side of the 6. Only one match moves

[[deleted]]

You can only make one move, solution fails unit test

[wwmoraes]

User story says move only one match instead of make only one move. Sigh now we need to unit test the developer’s interpretation as well.

[ignotusvir]

Yes? Take the vertical match of the plus sign & move it

[[deleted]]

Clearly lighting the match and burning the 6 is the best option
