How the fuck did an obvious math exercise with no errors get so many upvotes? Are Lemmy users really that knee jerk to upvote anything claiming to be AI?
If you have no idea, it’s best to hold back. It would have been easy to look up this type of problem, which is very common in elementary schools in Germany. Here’s an explanation of how “number walls” work (in German): https://de.wikipedia.org/wiki/Zahlenmauer
OP’s math problems are most likely AI-generated because they contradict the fundamentals of this type of problem.
Middle has two numbers. Given 340, what is a number that adds to 840.
Bottom is 3 numbers. Given two numbers, 120 and 80, what adds to 840?
Same for the second problem.
My kids are in Highschool now but I still remember problems like that from their elementary school days. There was no AI then. It’s as a pattern recognition exercise with addition and subtraction.
In math olympiads, like from 4th grade, it would be presented even more abstract by listing just the numbers and expecting you to fill in the blanks. By organizing the numbers it helps children see the pattern that’s expected so when they see it as list they can understand it better.
pretty sneaky way to mask your mistake. if your explanation is correct, then the second problem has 450 solutions (450,0|449,1|448,2…), which obviously is a stupid question then…
Asking a child for two numbers that add to X (450) is extremely common. You are so divorced from your childhood that you can’t remember the types of problems given to 8 year olds.
So yes, there are infinite correct answers. It makes it easier.
Top is 840, below that, we have 340+(500) to equal 840.
But the problem is that putting the 500 there means the number below that, to add up to 500, MUST be 420, which means the left side of the left puzzle is impossible, because 120 + 420 does not equal 340.

The way this exercise is supposed to be done is:
The idea is that the two supporting blocks below have the same “weight” as the block directly above.
I don’t know if this page was AI generated, but its clearly wrong.
Would you mind explaining how it works?
Top is 840.
Middle has two numbers. Given 340, what is a number that adds to 840.
Bottom is 3 numbers. Given two numbers, 120 and 80, what adds to 840?

“sneaky” GTFO
Asking a child for two numbers that add to X (450) is extremely common. You are so divorced from your childhood that you can’t remember the types of problems given to 8 year olds.

For the first problem.
Top is 840, below that, we have 340+(500) to equal 840.
But the problem is that putting the 500 there means the number below that, to add up to 500, MUST be 420, which means the left side of the left puzzle is impossible, because 120 + 420 does not equal 340.
