Excuse me.

5 - 7 = -2

bottom left and right corner being 1 and 9 respectively were my sure guesses

Yeah same.

Bottom right corner being 9 was a sure thing because of the x 45.

Bottom right corner being 9 was a sure thing because of the x 45.

And the -18

And bottom left must be 1 because of the multiplication

Same with the 1, but after that I struggled. I almost found a solution and then there had to be 3 different numbers in row 3 col 2.

Bottom right corner could have ended up being 3 too, which is what really threw me for a loop.

The fact that the high numbers are difficult to place made it somewhat doable to start with some guesses.

It's my PEMDAS that keeps fucking me up, since it doesn't apply but my math-mind keeps trying to force it that way from training.

It's possible, but less likely with the nearby minuses, since you need a 15 generated next to the 3 to make 45.

That’s what I thought, but it’s also possible after the division in the column you end up with a fraction, say 1/2, then multiply by 2 to get 1 as the answer.

This is when I gave up completely ha

Did anyone solve it?

the way i got around the pemdas distress was to actually write out what the equations for each row would be. And then that just made me feel intense, unyielding anger so i went back to trying to cross out numbers that dont fit each box

I did not solve it, no.
