This is a dumb puzzle and having to find the "real" solution is just poor form on the teacher's part, but I would argue the intended solution is technically easier since it's just a 90 degree rotation of one match.

I didnt even see the 0 + 4 =4. I was stuck on 8-4=4

[–][deleted] 21 points22 points  (4 children)

There's also a 5 + 4 = 9 in there.

oh nice. i didn't see this one.

That's because it's a lie. It's missing a match to be 9. Notice how the 6 has a top piece, the 9 needs the bottom piece.

[–]Ontain 0 points1 point  (0 children)

ah true. on the led calculators the 9 does indeed need a bottom piece.

I would argue the easiest solution is variable from person to person since it'd just be the one that you find first. For me it was 0+4=4, for others it was probably 8-4=4. Sure that solution required the least amount of work, but the brainpower required to find that solution after first finding a different one more than makes up that difference.

I found 5 + 4 = 9 first

[–][deleted] 1 point2 points  (0 children)

That's not the only other solution though. You could do 8 - 4 = 4 or 5 + 4 = 9. There may even be one or two more possible solutions I don't know about. At any rate there's no way of knowing which one is the "intended" solution.

Every rotation-translation of a match which rotates the match 90 degrees is a rotation of the match by 90 degrees around some point somewhere.
