What is the pattern?

Question

Mathematics

Here is a problem for 2nd grade.
It is necessary to cross out the extra numbers in each cloud.
What principle? Can someone explain, otherwise it's embarrassing in front of a child :)

Answer 1

The principle is that there is no wrong answer.

Answer 2

1) a single number ending in 4
2) a single number that ends at the bottom right
3) etc.
You understood the logic that it is not known what exactly the compilers mean

Answer 3

there are paired numbers between which the difference is 4, in 3m the wrong answer should be crossed out 12, not 6

Answer 4

I support. Otherwise, there is absolutely no logic here.
I’m a fucking adult with my own problems, I’ve already been sitting for an hour and trying to find a pattern.
I even found these textbooks ...
The only adequate explanation is based either on one / two-digit, or even / odd.
Multiplication takes place in the 2nd grade. So sir, you do not know the child))
