@@sethsolves5522 You don't actually need to put all the numbers in though. It's just used to illustrate. If you can spot that the 2 and the 6 can only go in those two spots then you know nothing else can. It's just the pigeonhole principle.
Because there has to be a 2 and a 6 in the 3x3 box(there has to be each digit from 1 to 9 in every row column and 3x3 box). Since those two boxes are the only ones that could potentially contain 2 and 6, they have to be either 2 or 6 because 2 and 6 can’t be in any other boxes in the 3x3 box. Basically, we know there has to be a 2 and a 6, and since those are the only potential options, 2 and 6 have to be in those two places.
Ive been stuck on a expert level for a few days. Finally found a helpfull tutorial, thanks!!
Its not hard to find the hidden pair.. but its hard to know which one belongs to which square
Max number i noted on cells are 3.
I honestly don't like putting too many numbers in a cell, specially when you are solving manually
It's upsetting because half the techniques in this playlist rely on you doing that though.

But in the same cell there are also 4 nad 8. Why not 4 and 8 ?!!!
bo 4 i 8 masz jeszcze, np. w pierwszej komórce, trzeciej i piątej, a 2 i 6 tylko w tych dwóch, więc nie może tu być inna liczba niż 2 i 6

Cause 4 and 8 are also in other cells from the same box
